Patent Number Title Of Patent Date Issued
7995930 Optical receiver using Mach-Zehnder interferometer August 9, 2011
The present invention relates to an optical receiver, in which the transmittance of a Mach-Zehnder interferometer can be locked at a normal operation point in a simple structure and control. A transmittance detecting circuit and a minute modulation signal detecting circuit are provid
6333942 Atomic frequency standard laser pulse oscillator December 25, 2001
An ultra-stable microwave output with less jitter than a prior art atomic oscillator is obtained and an ultra-short optical pulse train is generated with a repetition frequency stabilized at the same level as a time standard. The repetition frequency of a regeneratively mode-locked laser
