Silicon based light emitting devices
 An efficient solid state light emitting device wherein sulphur is used to provide isoelectronic centers in silicon which bind excitons which emit light at a wavelength of 1.32 microns (um) and are particularly adapted for use in integrated opto-electronic circuits and in launching optical signals in single mode optical fibers.
