Abstract

The edge-emitting LED (ELED) illustrated in Fig. 1 is an attractive source for medium capacity medium range optical fiber links. It combines the convenience in use of the LED with output power approaching that of the laser. In this paper an optimization of the simple oxide stripe ELED for maximum launched power is described. A technique for forming a lens on the end of a fiber has been developed to couple the ELED to a fiber mounted in a practical package as described in Fig. 2.
