A SEMICONDUCTOR DEVICE COMPRISING: A BODY OF SEMICONDUCTOR MATERIAL INCLUDING EMITTER. BASE AND COLLECTOR REGIONS; A FIRST P-N JUNCTION BETWEEN SAID EMITTER AND BASE REGIONS FOR GENERATING RECOMBINATION RADIATION IN RESPONSE TO A FORWARD VOLTAGE APPLIED ACROSS SAID FIRST JUNCTION, AND A SECOND P-N JUNCTION THEREIN BETWEEN SAID BASE AND COLLECTOR REGIONS FOR GENERATING A PHOTOCURRENT IN RESPONSE TO SAID GENERATED RECOMBINATION RADIATION, BOTH OF SAID JUNCTIONS BEING NON-ABRUPT AND NONTUNNELLING,
