SKU: SLED
The SLED series laser diodes are fabricated in hermetically sealed 14-pin or 8-pin butterfly packages. The laser diodes contain a monitor photodiode, thermoelectric cooler (TEC), and a thermistor to secure high-quality laser performance. Our laser products are Telcordia GR-468 qualified and in compliance with RoHS Directives. SLEDs are based on generation and amplification of spontaneous emission in a semiconductor. It emits a single mode with a wide spectrum and low coherence. SLEDs are highly susceptible to back-reflections which are amplified inside, resulting sin pikes or damage to the device. For wavelength >1310nm, it contains an optical isolator inside. We produce special ultra-broadband external fiber isolators for wavelengths <1310nm. SLEDs operating in the wavelength <1400 nm are based on a bulk material with low polarization dependence, consequently offering a PM-coupled device with high polarization extinction stability. SLED operating in the 1550 and 1620 nm are based on quantum well that has a strong polarization-dependent gain.
Due to their high spatial resolution, SLEDs are widely used in interferometric sensors, such as Optical coherence tomography (OCT), Fiber sensors, Fiber Optic Gyroscope (FOG).
