ABSTRACT:
A light emitting semiconductor device and a light detecting semiconductor device are coupled optically with each other through a light guide. The light guide is made of a single piece of light transmissible insulating material and at least its end portion associated with the semiconductor light detector is brought into wet contact with a light sensing region of the semiconductor light detector including its neighboring area. While being in fluid state, the light transmissible insulator held in wet contact with the semiconductor light emitter and detector is shaped into a predetermined configuration and thereafter hardened to form the light guide.
