ABSTRACT:
A method for driving an optoelectronic switching device such as a pnpn semiconductor device comprises applying a predetermined biased voltage to the optoelectronic semiconductor device, and supplying plural light inputs to the optoelectronic semiconductor device to which the predetermined biased voltage is applied. The plural light inputs are supplied to the optoelectronic semiconductor device intermittently with a predetermined period before carriers excited by a first input pulse of the plural light inputs become extinct. As a result, the number of light sources is decreased.
