摘要： An arrayed waveguide grating for easily changing the ratio of distribution of an optical signal into the main optical signal and the monitored optical signal is disclosed. In the device, an optical signal incident on an input waveguide is input into an arrayed waveguide via an input-side slab waveguide and is divided into main optical signals having different wavelengths in the arrayed waveguide with respect to a diffraction order m (natural number), and the divided optical signals are transmitted through an output-side slab waveguide and converged on output waveguides. The device has monitoring waveguides for monitoring optical signals having corresponding wavelengths of the main optical signals, where the monitored optical signals are diffracted in the arrayed waveguide with respect to a diffraction order m+i or m−i (i is a natural number), and the arrayed waveguide has a taper structure in the vicinity of the joint of the arrayed waveguide and the output-side slab waveguide, in which the width of each waveguide gradually changes along the direction of light transmission so as to adjust the ratio of distribution into the main optical signal and the monitored optical signal.

摘要： An optical circuit device includes a directional coupling section and at least one diffraction grating. The directional coupling section is comprised of first and second optical waveguides and having a length n times (n is an integer equal to or larger than two) the minimum length required to completely couple light inputted to the first optical waveguide with the second optical waveguide. The diffraction grating is formed in the directional coupling section and has a specific reflection characteristic. When input light beams having different wavelengths are inputted to the input side of the first optical waveguide, light having a reflection wavelength in the diffraction grating is demultiplexed/outputted to the input side of the second optical waveguide. Light beams having other wavelengths are outputted to the output side of the first or second optical waveguide. When the light having the reflection wavelength in the diffraction grating is inputted through one of the output sides of the first and second optical waveguides from which the light beams having other wavelengths are not outputted, the light having the reflection wavelength input through the output side of the optical waveguide is multiplexed with the output light beams having other wavelengths.
