Abstract

PURPOSE: To make it possible to construct a one-directional optical detecting element, which is highly sensitive and has a small dark current and which has a wide range of frequency characteristics, and to increase the change-over frequency of an optical switch to a high speed in accordance with the wide range by using a photoelectron multiplier as an optical detector.
