ABSTRACT:
In accordance with the invention, an improved optical communication system employs light-generating devices comprising a phonon-tuned crystal alloy host doped with an optically active atom. In one embodiment, the crystal alloy host and optically active atom respectively comprise spinel and nickel. The spinel material is typically a solid solution between magnesium aluminate and magnesium gallate.
