1000nm fiber coupled superluminescent diode SLD 25mW

Radiant light-emitting diode (LED) is a semiconductor optoelectronic device located between laser diode (LD) and light emitting diode (LED). Similar to laser diode, superluminescent light-emitting diode is based on electrically driven pn junction. When forward biased, the pn junction has optical activity and generates amplified spontaneous emission over a wide wavelength range. The peak wavelength and intensity of SLD depend on the active material composition and injection current level. SLD is designed to have high one-way amplification for spontaneous emission generated along the waveguide, but unlike laser diodes, feedback is not sufficient to achieve laser action
