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.

摘要： The invention provides an apparatus for and method of monitoring wavelength multiplexed signal light, which can obtain monitored data for multi-channel optical signals contained in the wavelength multiplexed signal light, which can avoid a large size and complicated structure and high cost of monitoring apparatus, and which can easily monitor the wavelength multiplexed signal light. The invention also provides an optical transmission system employing the monitoring apparatus and method. An optical filter being able to control a loss pattern is disposed on a monitoring waveguide for the wavelength multiplexed signal light, which is branched for monitoring from an input waveguide and an output waveguide constituting a main optical transmission path in a wavelength multiplexed signal light monitoring apparatus. While the optical filter sets a plurality of loss patterns in sequence, the wavelength multiplexed signal light having passed through the optical filter is detected by a photodiode for each of the loss patterns, and monitored data of the wavelength multiplexed signal light can be obtained from detected data.
