SEMICONDUCTOR LIGHT SOURCES,
Abstract
The development of semiconductor light sources and the applications of such sources were the objectives of this project. Some 250 GaAs diodes were prepared, most of these exhibited injection electroluminescence, and a few appeared to be capable of producing coherent radiation. Modulation of the light output at frequencies up to 10 Mc/s has been achieved. Study of these semiconductor light sources for photographic recording of data at high information rates was undertaken. Recordable data at frequencies up to 350 Kc/sec have been demonstrated with possibilities of extending this capability into the megacylce range. Multielement light sources have been fabricated to demonstrate the possibility of simultaneous multichannel recording of data. (Author)
