GDF Germanate Glass Core Optical Fibers

Wavelength 600-2300 nm; Bandwidth 0.05-1.2 nm; Reflectivity 5-99%; SLSR >8 dB; Fiber Type SM, PM, Double Clad, LMA, Custom; Fiber Pigtail Length ≥0.5, CustomFiber Bragg gratings (FBGs) are sensitive to changes in temperature, their thermal sensitivity is about 6.7 ppm/K (+0.11 pm/K @1550 nm). Greitlex Photonics’ GTL-FBG-AP-850 athermal packaged fiber Bragg gratings are intended for passive compensation of the FBG’s thermal sensitivity by matching the case elements’ expansion with the FBG’s wavelength shift under the influence of temperature. This technology allows customers to achieve all advantages of fiber Bragg gratings, while preserving a high wavelength stability within a wide temperature range.The following configurations can be changed at the customer's request, please contact AMS Technologies to discuss a customized athermal packaged fiber Bragg grating solution tailored to your project’s requirements.These FBGs replace similar products from the former FORC Photonics.

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.

Ridge Waveguide Fabry-Perot Laser Diodes; 808-1060 nm; Spectral Width 0.3-3 nm; Output Power 100-800 mW; Threshold Current ≤70-300 mA; Slope Efficiency 0.8, 0.9 W/A; Forward Current 170 to 1,500 mAToptica eagleyard’s RWL series of Fabry-Perot ridge waveguide laser (RWL) diodes operate on a single transverse resonator mode. This leads to high power output (100 up to 800 mW in cw mode) with diffraction limited beam profile. However, multiple axial (longitudinal) modes may occur which can lead to differing optical frequencies. The frequencies are separated by the free spectral range of the resonator given by the reflecting facets of the laser chip.Additional features such as collimation optics for optimum beam quality or a thermoelectric cooling module for more stable frequency performance can be integrated in the package on request. Direct temperature control of the chip enables optimum wavelength stability and better heat dissipation under continuous high-power operation.Key Features:Fabry-Perot Edge-emitting Ridge Waveguide Laser DiodesBroad Wavelength Range: 808 to 1060 nmTyp.
