An arrayed waveguide grating of the present invention comprises a first circuit A and a second circuit B. When multiplexed lights are inputted from a fiber array which is connected to input/output waveguides at multiplex side, the multiplexed lights propagate through the input/output waveguides at multiplex side, and are outputted to a slab waveguides at multiplex side. The outputted multiplexed lights are spread in a radial pattern and inputted to an arrayed waveguide group by equally segmented optical power, and then outputted to slab waveguides at demultiplex side being provided with phase shift at the fixed difference in length. Demultiplexed lights outputted to the core of input/output waveguides at demultiplex side, generating a multiple beam diffraction interference at the slab waveguides at demultiplex side, are outputted into an optical fiber of a tape fiber by the fiber array. Consequently, miniaturization and lowering the price are realized, and there will be less limitation in the mounting space and the mounting position.
