Latest Patents
Fumiaki Saitou holds a patent for an "Optical receiver using Mach-Zehnder interferometer." This invention relates to an optical receiver that allows the transmittance of a Mach-Zehnder interferometer to be locked at a normal operation point with a simple structure and control. The design includes a transmittance detecting circuit and a minute modulation signal detecting circuit, which are provided in parallel after a balanced optical receiver. A switch is selectively connectable to either the minute modulation signal detecting circuit or the transmittance detecting circuit. During the initial stage of frequency pull-in, the switch connects the transmittance detecting circuit to the synchronous detection circuit. If the transmittance detecting circuit identifies that the transmittance of the Mach-Zehnder interferometer at the carrier frequency reaches the desired level, the switch connection is changed to the minute modulation signal detecting circuit. Fumiaki Saitou has 1 patent to his name.
