摘要： An optical multi/demultiplexer having a desirable multiplexing-and-demultiplexing performance throughout the entire wavelength band for signal transmission, and an optical multiplexer whose multiplexing performance is less susceptible to the shift of the center wavelength and to the fluctuation of the center wavelength due to temperature change and whose optical circuit can be miniaturized. The optical multi/demultiplexer comprises a substrate and an optical circuit formed on the substrate. The optical circuit comprises a circuit having a wavelength dependency, which may be a Mach-Zehnder interferometer (MZI), and a Y-junction. In one aspect of the optical circuit, the Y-junction is connected to one end of each of the two optical waveguides included in an MZI. In another aspect of the optical circuit, the Y-junction is connected to one end of an optical waveguide included in an MZI and to one end of another optical waveguide, whether it is independent or belongs to another MZI.

摘要： The present invention relates to an optical component and others in structure capable of implementing improved compensation for a gain slope. The optical component is equipped with first and second Mach-Zehnder interferometers. The first Mach-Zehnder interferometer is provided with a first temperature controller for controlling a temperature of at least one of a part of an optical main path and a first optical side path, while the second Mach-Zehnder interferometer 42 is also provided with a second temperature controller for controlling a temperature of at least one of a part of the optical main path and a second optical side path. A filter circuit having a wavelength-dependent insertion loss is disposed between the first and second Mach-Zehnder interferometers, and a controller controls the temperatures of the optical paths by use of the first and second temperature controllers on the basis of the insertion loss of the filter circuit, thereby setting a loss for light of a predetermined wavelength propagating between a light input end and a light output end.

摘要： A main optical path and an auxiliary optical path which are formed in a substrate are optically coupled to each other with a plurality of optical couplers, so as to constitute a Mach-Zehnder interferometer. By controlling the temperature regulation of main and auxiliary optical paths effected by heaters, a control unit regulates the transmissivity of light across an optical input end and an optical output end. Respective optical path lengths of the main and auxiliary optical paths are set so as to lower birefringence when optical loss becomes greater.
