There are many variations on device structure in this region, but all use a form of Aluminum Gallium Arsenide (AlGaAs) or Gallium Arsenide (GaAs) materials. There is still a push to increase the efficiency of these devices, but the increases are only incremental improvements. Applications include infrared (IR) remote controls, night vision illumination, industrial photocontrols and various medical applications (at 660nm - 680nm).
