摘要
In the Mach-Zehnder interferometer type optical circuit in which a plurality of Mach-Zehnder interferometers have been provided, between the Mach-Zehnder interferometers a and b, there are provided a plurality of grooves 27(a-b)1, 27(a-b)2 and an endothermic wall 28(a-b). Since heat generated from the temperature control device 25a mounted on the waveguide arm of the Mach-Zehnder interferometer a is absorbed by the endothermic wall 28(a-b), an influence due to heat interference to be exerted on the Mach-Zehnder interferometer b is restrained.
