Cut off Wavelength 650, 1000 nm; Mode Field Dia. 2.0, 4.3 µm; Zero-dispersion Wavelength 800 to 1000 nm; Optical Loss <30, <100 dB/kmGreitlex Photonics’ HN-PCF series is a new type of fibers, so-called micro-structured or photonic crystal fibers. This type of fibers features holes or inclusions of a material with different refractive index in the core and/or in the cladding.New dispersion and nonlinear properties can be observed in photonic crystal fibers. Most of the specific applications for micro-structured fibers require their own specific structure of the fiber. Greitlex Photonics has the capabilities to design and fabricate a broad variety of fiber structures according to customer orders.Other parameters are available on the request.The HN-PCF-800 fiber is specially designed for supercontinuum generation using Ti-sapphire ultra-fast femtosecond lasers, while the HN-PCF-1040 fiber is specially designed for supercontinuum generation using Yb-doped picosecond or femtosecond ultra-fast fiber lasers.

Numerical Aperture 0.09; Core Dia. 20 µm; Cladding Dia. 127 µm; Gray Loss <20 dB/km; Polarization Extinction Ratio >20 dBGreitlex Photonics’ SBS-DC series of SBS-suppressed optical fibers feature a suppressed stimulated Brillouin scattering gain. Stimulated Brillouin scattering (SBS) is the major factor limiting maximal power of narrow-band fiber lasers (less than 100 MHz linewidth). It is especially crucial in applications which require small mode field diameter (MFD), i.e. Raman amplifiers. Suppression of SBS gain, while maintaining MFD (and Raman gain) becomes a very important task in such fibers. Another promising application of single-frequency lasers is LIDAR (Light Detection And Ranging). In the case of all-fiber systems, it is the passive fibers at the amplifier output (pigtails of isolators, circulators, collimators) that limit the maximum achievable peak power. Thus, development of large mode area (LMA) passive fibers with increased SBS threshold (as compared to standard LMA fibers) is more and more critical for those applications. To suppress SBS gain for a fixed MFD, Greitlex Photonics uses a specially designed multi-layer, multi-components doped core. It allows to suppress SBS gain by 3 to 5 dB relative to standard, uniformly doped Ge-doped passive fibers with the same MFD. The developed method allows Greitlex Photonics to design custom dopants distribution over the core to suppress SBS by 3 to 5 dB for most of the actual optical refractive index profiles (any core numerical aperture and diameter). The SBS-DC-20/125-1550PM polarization maintaining (PM) fiber has been specially designed to be used in pigtails of output components (isolators, collimators, pump-and-signal combiners etc.) of high peak-power single-frequency lasers operated near 1550 nm. The fiber is intended for utilization in systems with the ability to maintain polarization. Fibers with suppressed SBS-gain for a custom designed operating wavelength, core numerical aperture (NA) and diameter are available on request. Please contact AMS Technologies to discuss your customized SBS-suppressed optical fiber solution.

Greitlex Photonics’ series of specific application FBGs are widely used for applications like in-fiber mirrors or optical filters with narrowband optical spectrum. Fiber Bragg gratings also are one of the most popular elements in the field of fiber-optic sensing.Within Greitlex Photonics’ series of specific application fiber Bragg gratings (FBG) you find:Wavelength Locker FBGsWDM ITU Filter 100/200 GHz FBGsRaman Laser FBGsFabry-Perot Interferometer FBGsHard Environment FBGsRadiation Hard FBGsGTL-FBG-WL-810 wavelength locker fiber Bragg gratings are used as external reflectors for laser diodes. With the help of these FBGs it is easy to stabilize the wavelength generation of pump semiconductor lasers and single-frequency lasers. Low-reflection gratings with a full width at half maximum (FWHM) bandwidth of 0.3 nm to 0.8 nm and a reflectivity of 2% to 5 % are ideal for stabilizing pump power lasers. FBGs with FWHM bandwidths around 0.1 nm and reflections of 10% to 20% are used close to semiconductor laser crystals for creation of single-frequency sources. Greitlex Photonics provides wavelength locker FBGs with very accurate wavelength positions (up to ±0.02 nm).Greitlex Photonics’ GTL-FBG-WDM-810 series of WDM ITU Filter 100/200 GHz fiber Bragg gratings with narrow spectral bandwidth are good elements for filtering optical signals. Such FBGs are widely used as optical add/drop multiplexer in WDM systems. A high level of SLSR is allowed to avoid adjacent channel crosstalk in systems. These FBGs feature a flat-top reflection spectrum and steep spectral roll-down. Athermal packaging of the FBG with wavelength stability <0.16 nm for a temperature range of 0°C to +70⁰C is required for stable operation.Highly efficient multi-cascaded Raman lasers based on phosphosilicate fibers can be created at different wavelength using our GTL-FBG-RL-880 Raman laser fiber Bragg gratings. Compared to Germanium-doped fibers, an approximately three times larger Raman shift can be achieved.For many applications where very small temperature or strain changes have to be measured using acoustic waves, the sensitivity can be enhanced by using pairs of FBGs. A Fabry-Perot interferometer based on Greitlex Photonics’ GTL-FBG-FPI-810 Fabry-Perot interferometer fiber Bragg gratings is such a pair of FBGs, allowing to detect a small phase shift. By coating the fiber between the gratings with an electric, magnetic or acoustic enhancing coating, very small changes of these fields can be measured. For sensing purposes and to evaluate small vibration or acoustic signals via an interferometric method, it is often sufficient to work with a low-finesse Fabry-Perot cavity.GTL-FBG-HE-810 hard environment fiber Bragg gratings can be provided as separated or chains of FBGs with different wavelengths, allowing for multipoint temperature monitoring. Different types of single mode (SM) optical fibers and fiber coatings can be used for writing these gratings. High-temperature acrylate coated fibers apply for temperature ranges up to +150°C. Polyimide or metal (Cu, Al) coated fibers are used for high-temperature applications with maximum temperatures of +300°C and +500°C respectively. Using a steel tube protection, our hard environment FBGs can be applied up to +700°C.GTL-FBG-RH-880 radiation hard fiber Bragg gratings written in radiation resistant pure silica core fibers are ideal for applications in the atomic energy industry, aerospace and other radiation intense environments.All those FBGs replace similar products from the former FORC Photonics.

Greitlex Photonics’ series of standard types FBGs are widely used for applications like in-fiber mirrors or optical filters with narrowband optical spectrum and can act as a sensor element for strain and temperature measuring.Within Greitlex Photonics’ series of standard types fiber Bragg gratings (FBG) you find:Uniform Fiber Bragg GratingsApodized Fiber Bragg GratingsChirped Fiber Bragg GratingsApodized-chirped Fiber Bragg GratingsFiber Laser Matched Fiber Bragg GratingsTilted Fiber Bragg Gratingsπ-Phase-Shifted Fiber Bragg GratingsGTL-FBG-UF-810 uniform fiber Bragg gratings are produced with grating lengths from 0.5 mm to 10 mm. Such gratings show their full width at half maximum (FWHM) from 0.015 nm (R = 25%) to 0.03 nm (R = 90%) for 633 nm wavelength (0.1 nm and 0.17 nm at 1580 nm) and gratings length 9 mm. Standard uniform FBGs have a bandwidth of 0.15 nm to 0.6 nm, a reflectivity of 5% to 99% and grating lengths of 1 mm to 3.5 mm.Fiber Bragg gratings are sensitive to changes of strain and temperature. Uniform FBGs can be provided as separated units or chains of FBGs with different wavelengths. By using chain FBGs, multipoint monitoring of temperature, strain or other physical parameters is available. Different types of single mode optical fibers and fiber coatings are used. Acrylate coated fibers for normal temperature range of -40˚C to +100˚C. Polyimide or metal (Cu, Al) coated fibers are used for high-temperature applications with maximum temperatures of +300˚C and +500˚C respectively.GTL-FBG-AD-820 apodized fiber Bragg gratings show a special profile of induced refractive index and grating strength along the grating length. Therefore, the side lobes level becomes smaller compared to ordinary gratings. There are a lot of apodized profiles which lead to the optimization of various FBG parameters (strength, FWHM, side lobe suppression ratio (SLSR)). Apodized FBGs are useful in sensing applications, signal and Brillouin scatter filtering and others. Possible value of SLSR for different grating strengths is -10 dB to -30 dB.Our GTL-FBG-CR-840 chirped fiber Bragg gratings feature a linear variation of the FBG period along the grating length. Chirped FBGs are manufactured by using a non-periodic phase mask. The available chirp rate of the phase mask period can range from 0.01 nm/cm to 30 nm/cm. Therefore, such FBGs have a wide spectrum bandwidth and special dispersion characteristics. Chirped FBGs are useful for gain-flattening EDFA and ASE light sources, band stop filters, in ultrafast mode-locked fiber lasers, powerful lasers, and chromatic dispersion compensation telecom systems.Apodization of chirped FBG is necessary to obtain FBGs with a smooth reflection spectrum. There are several apodization profiles that lead to the optimization of various parameters of the FBG such as reflection coefficient, FWDM, side lobe suppression ratio (SLSR), or the parameter of dispersion. In chirped FBGs the dispersion is determined by the rate of change of the period along the length of the FBG. Within the GTL-FBG-ADG-820 series of apodized-chirped fiber Bragg gratings, FORC Photonics has implemented several types of apodization profiles: Sine, Gauss, Semi Gauss and Super Gauss.The simplest type of apodization is "Sine", which "saves" the length of the FBG and provides a (SLSR) value of about 20 dB. The "Gauss" apodization function provides the best SLSR value in the order of 30 dB. For many applications, such as pulsed fiber lasers, there are special requirements for the dispersion value and the shape of the reflection profile. "Gauss" apodization of chirped FBGs allows to obtain excellent results in these applications. The "SuperGauss" type of apodization is intended for obtaining a flat-top reflection spectrum. Apodized FBGs are useful in sensing applications, signal and Brillouin scatter filtering and others.Our GTL-FBG-LP-830 fiber laser matched FBG pairs are an ideal solution for fiber laser fabrication. Minimum insertion losses and other parameters are optimal for lasers with output powers of several tens of W. High- and low-reflection gratings are available, with the high-reflection grating showing -20 dB levels of about 0.5 nm to 0.7 nm. The low-reflection output grating with 5% to 40% reflectivity has FWHM values of 0.15 nm to 0.35nm. The mismatching of LR relative to HR grating is up to ±0.15 nm. For narrow-line fiber lasers we provide FBG pairs with FWHM values around or below 0.1 nm for ideal matching without adjustment.GTL-FBG-TL-860 tilted fiber Bragg gratings have an angle between the wave vector of the grating and the fiber axis. Therefore, cladding modes resonance peaks become more intensive compared to ordinary gratings. The wavelengths of tilted fiber Bragg gratings cladding modes resonances are highly sensitive to the refractive index of the medium outside the fiber cladding. TFBGs are useful in sensing applications. Possible values of the tilt angle are 1⁰ to 45⁰.GTL-FBG-PS-870 π-phase-shifted fiber Bragg gratings have a very narrow peak within their transmission/reflection spectrum. Phase-shifted FBGs are gratings with a phase defect in the center. While the grating length determines its bandwidth, the spectral width of that peak depends on the strength of the FBG’s both parts. Typical FWHM values for our π-phase-shifted fiber Bragg gratings are 0.1 nm to 0.005 nm. A typical application of phase-shifted FBGs are narrow-bandwidth optical filters for single-frequency fiber lasers.All these FBGs replace similar products from former FORC Photonics.
