Abstract: PURPOSE: A multi/demultiplexer is provided to eliminate an additional device for regularizing a loss by regularizing a minimum loss of an output waveform using an offset. CONSTITUTION: The device is composed of a substrate(51), the first arrayed waveguide(52), the second arrayed waveguide(54), a slab(55), and an optical arrayed waveguide grating(53). The first arrayed waveguide and the second arrayed waveguide comprises a linear arrayed waveguide of an input side, a linear arrayed waveguide of an output side, and a curved arrayed waveguide of an output side respectively. An offset of specific value is provided to a connecting portion between the curved arrayed waveguide and the linear arrayed waveguide. If a signal light of a constant mode progresses along an optical waveguide, the intensity distribution in the curved arrayed waveguide and the intensity distribution in the linear arrayed waveguide are different. The disagreement of the intensity distribution causes the transfer loss of the signal light at the connecting portion between the curved arrayed waveguide and the linear arrayed waveguide. Since the offset of specific value is provided to the connecting portion between the curved arrayed waveguide and the linear arrayed waveguide, it is possible to minimize the transfer loss.
