Abstract
Disclosed is an optoelectronic semiconductor comprising a semiconductor substrate, a first insulating film covering the major surface of the semiconductor substrate and a second insulating film having electronic charge-storing means and lying on the first insulating film. When an optically guided wave is propagated to the first or second insulating film in the direction parallel to the major surface of the semiconductor substrate, an interaction is caused between the electronic charges stored in the charge-storing means and the optically guided wave, thereby allowing the optically guided wave to be modulated and the electronic charges to be released.
