Abstract: An optical transceiver for transmitting optical data to an optics communication channel and receiving optical data from the optics communication channel is disclosed. The transceiver includes a light sensor, a light emitter, and an interface between the optical transceiver and the optics communication channel. The light sensor is substantially optically isolated from the light emitter. Electrical data is transmitted responsive to the light sensor, and sufficient electric current is supplied to the light emitter responsive to received electrical data.

Abstract: A radiation sensitive solid state device employing a lateral current and a method for shortening the turn-off time of a radiation sensitive device are disclosed. The device includes a semiconductor layer of one conductivity type and a radiation sensitive element present in the semiconductor layer. The semiconductor layer forms a low resistance lateral path beneath the radiation sensitive element. The method for shortening the turn-off time includes providing a substantially lateral flow of carriers characteristic of the one conductivity type through the semiconductor layer beneath the radiation sensitive element.
