GTL-FBG-TB-890 Tunable Fiber Bragg Gratings

Wavelength Range 1.0-5.0 µm MWIR; Detector Size 1x1, 2x2 mm; Time Constant <2 µs; Responsivity 9x103, 4.5x103 V/W; Element Resistance 0.1-2.0 MΩ New Infrared Technologies’ (NIT) LEPTON Series of single-pixel VPD PbSe MWIR detectors are available uncooled as well as with integrated TECs (thermoelectric cooling elements), with different geometries, packaging solutions and preamplifier boards. LEPTON Series single-pixel detectors come in two standard sizes: 1 mm × 1 mm or 2 mm × 2 mm. LEPTON Series uncooled single-pixel PbSe MWIR detectors can be ordered packaged in SMD or TO-5 housings (with cap, hermetic) with sapphire window. These detectors are operational at room temperature and don’t require any cooling devices. LEPTON Series cooled single-pixel PbSe MWIR detectors are hermetically packaged in a TO-8 can housing with cap and sapphire window and include one or two thermoelectric cooler (TEC) stages for higher sensitivity as well as a thermistor. A calibration curve for the thermistor is available. NIT’s LEPTON Series also includes two low-noise preamplifier boards that are 5-V-powered via mini-USB connector: The LEPTON ANALOG PREAMP provides rotary switches to manually select the detector biasing voltage (4 steps from 1.25 V to 10 V) as well as the transimpedance gain (4 steps from 104 to 107 V/A). This preamp outputs a ±10 V analog voltage on a BNC connector. The LEPTON PREAMP WITH USB OUTPUT allows to digitally select the values for detector biasing voltage and transimpedance gain via software. Here, the output is a digital 14 Bit signal with a maximum sampling rate of 20 ksps. This preamp also features an analog output for the preamplifier stage on SMB or BNC connector. For more pixels, linear and two-dimensional array MWIR cameras are available from New Infrared Technologies – please refer to the LUXELL series of linear array MWIR cameras and TACHYON series of high-speed imaging MWIR cameras respectively.

Wavelength 600-2300 nm; Bandwidth 0.1-1.2 nm; Reflectivity 0.5-99.9%; SLSR ~8, ~10 dB; Fiber Type SM, PM, Double Clad, LMA, Radiation Resistant, Custom; Fiber Pigtail Length ≥0.5, CustomFiber Bragg gratings (FBGs) have many applications in optical communication, laser technique and sensing systems. 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.
