Semiconductor light emission system

Abstract From the Canadian patent

A semiconductor light emission system comprising, a semiconductor laser part constituted of a second conductive current restricting layer with a striped groove perforated therein, a first conductive clad layer, a first or second conductive active layer a second conductive clad layer on a first conductive substrate, and a second conductive - first conductive - second conductive bipolar transistor part constituted of said second conductive current restricting layer, first conductive clad layer, first or second conductive active layer, second conductive active layer in a position other than the semiconductor laser part.
