Abstract
The semiconductor layer of an opto-electronic device has one or more films of a pnictide rich material deposited thereon. The pnictide has a smaller reflective index than the semiconductor layer. These films provide a wave-guiding effect to light within the semiconductor layer in opto-electronic devices, such as solid state lasers and light emitting diodes and wave guides interconnecting such devices.
