ABSTRACT:
Disclosed is a semiconductor light emitting diode (LED) array in which "cross-talk" between adjacent diodes in the array is minimized. The disclosed LED arrays have an absorbing layer on the backside of the devices and/or a guard ring region surrounding each device in order to absorb spurious reflections within the semiconductor crystal. Disclosed also is a method of making improved light emitting diodes (LED's).
