Laser Diodes & Sources
Super Luminescent Light Emitting Diode (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.

System integration
Integration and compatibility
Use these checks to connect Super Luminescent Light Emitting Diode (SLED) to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM28, PM1310, PM1550, Hi1060, PM1950, PM980, PM850, SM800, 780HP, PM780 · Fiber Buffer: 0.9mm Tube, Bare
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 850nm, 1060nm, 1310nm, 1450nm, 1550nm, 1600nm, 1650nm, 930nm
- Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
