Abstract:
A demultiplexing unit that is provided in an optical device and performs demultiplexing into a plurality of optical signals having wavelengths different from each other includes a plurality of optical filters that are coupled in multiple stages and in which a period of a peak wavelength of a transmission spectrum differs among different stages, a monitoring optical filter coupled to one of the plurality of optical filters, a monitoring photodetector coupled to the output side of the monitoring optical filter, and a plurality of wavelength adjustment units that are provided individually for the plurality of optical filters and the monitoring optical filter and cause wavelength shifts of an equal amount in a same direction.

Claim (Index 9):
The optical device according to  claim 2 , wherein\n the plurality of optical filters have such optical path length differences that, in comparison with the optical path length of the optical filter in a certain stage, the optical path length difference of the optical filter in a stage at the input side by one stage is doubled; and the monitoring optical filter is provided between each adjacent ones of the stages of the plurality of optical filters and has the optical path length difference equal to that of the optical filter in the stage at the input side by one stage.
