The NIR 830 Superluminescent Diodes SLD that operates in a true inherent superluminescent mode. This superluminescent property generates broader band at higher drive currents in contrast to other conventional SLED which are ASE-based, here high drive tends to give narrower band. Its low coherence reduces Rayleigh backscattering noise. Coupled with high power and large spectral width, it offsets photoreceiver noise and improves spatial resolution (in OCT) and measurand sensitivity (in sensors). The SLED is available in 14-pin butterfly package. It is compliance with the requirements of Bellcore Document GR-468-CORE.

The Panda 1um Polarization Maintaining Double Clad Passive Matching Fiber is designed for ultrashort pulse fiber lasers, high-power narrow-linewidth fiber amplifiers and other scenarios. It has the characteristics of high matching, low fusion loss, and high polarization extinction ratio, ensuring the high-performance application of polarization-maintaining ytterbium-doped fiber in the system.

BoxOptronics 1060nm 1480nm polarization independent Optical Isolator is a fiber-coupled in-line polarization-independent isolator that transmits all polarized light (not just the light polarized in a specific direction) efficiently in one direction but block transmission in the opposite direction, It is widely use in protect against reflections, which can corrupt some measurements or damage lasers and amplifiers. This 1060nm 1480nm polarization independent Optical Isolator can be single or double/dual stage depending on the degree of required optical isolation of the propagating light.

The DWDM DFB Butterfly analog Laser Diode For CATV Application is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback chip that has been designed specifically for Radio Frequency (RF) applications. The DWDM DFB Butterfly analog Laser Diode has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. The versatile DWDM DFB Butterfly analog Laser Diode reduces cable network architecture fiber needs and lessens equipment requirements in the hub.

The 974nm 600mW Pump Laser Diode are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. Devices are available with kink free output powers to 600mW. The 976nm 600mW PM FBG Stabilized pigtailed butterfly Pump laser diode series pump module utilises a Fiber Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes.

The high power 1653.7nm Laser module utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in a epoxy-free and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode to secure high quality laser performance. 1653nm 40mW BTF laser diode for methane gas detection are Telcordia GR-468 qualified, and in compliance with RoHS directives.
