Abstract
The invention provides an optical functioning device which emits and receives light, and a driver circuit for controlling the device with light. In the device, elements, in which semiconductor multilayer-film reflecting mirrors are provided at both the upper and lower ends of a pnpn structure of semiconductors and which have light-emitting and light-receiving functions to act as optical resonators, are integrated two-dimensionally each with electrodes which are provided for the and the transistors act as phototransistors into which light is introduced.
