A superluminescent diode (SLED or SLD) is an edge-emitting semiconductor light source based on super luminescence. It combines the high power and brightness of laser diodes with the low coherence of conventional light-emitting diodes. LD-PD has been designing and fabricating SLEDs in our fab, in the 1200 to 1700nm wavelength range, we have the highest power & widest bandwidth devices in the industry.
Recognizing the need for SLEDs with Low Degree of Polarization for the FOG and FBGL sensing markets,LD-PD has now developed a range of devices to meet the demanding specifications of these markets.
