| 英文摘要 | The present invention provides a lightwave circuit device, an optical multiplexer, and an optical demultiplexer with which light can be multiplexed or demultiplexed even when a plurality of lightwaves of varying wavelength are inputted. The lightwave circuit device includes first to third Mach-Zehnder interferometers. The first to third Mach-Zehnder interferometers each have first to third ports, a first optical coupler, first and second optical waveguides, a second optical coupler, and a first heater provided along at least one of the first and the second optical waveguides. The second port of the first Mach-Zehnder interferometer and the first port of the second Mach-Zehnder interferometer are optically coupled, and the third port of the first Mach-Zehnder interferometer and the first port of the third Mach-Zehnder interferometer are optically coupled. |
