Abstract:

This report concerns the development of superluminescent LEDs SLEDs for use with graded index multimode fibers. The basic technical objective is to develop a SLED which can couple at least 500 micro of power into a standard 0.20 NA 50-micrometers core graded index fiber at a drive current not exceeding 200 mA. The basic technical objectives have been net and exceeded. The only remaining task is to mount a number of devices in a standard package with thermo-electric cooler TEC and graded index fiber pigtail. Keywords Laser Superradiant Spectral width Antireflection coating, Light emitting diodes.
