OPTICAL PULSE GENERATOR

摘要

The object of the present invention is to provide an optical pulse generator which very stably generates for a long period of time a high cycling frequency o ptical pulse chain. In order to obtain this object, in a ring type resonator R, the pre sent invention provides an optical path length regulator 14 which performs high preci sion optical path length adjustment and an optical path length regulator 60 which per forms wide range optical path length adjustment, and extracts a clock signal by conver ting an optical pulse emitted from the ring type resonator R to an electrical signal by a clock extractor 42, detects the frequency difference between a base frequency signal o utput form a synthesizer 52 by a frequency difference detector 50, and controls said o ptical path length regulator 14 and said optical path length regulator 60.
