Provided is a waveguide-type optical diffraction grating. A waveguide core includes a waveguide core that is asymmetric with respect to a thickness direction perpendicular to a light propagating direction. In the waveguide core, a phase adjustment portion is configured to adjust a phase difference between a forward wave traveling in an input direction and a reflected wave traveling in a direction reverse to the input direction in the waveguide-type optical diffraction grating, and the phase adjustment portion is provided in a manner that a sum of a phase of the forward wave and a phase of the reflected wave which are generated in the phase adjustment portion becomes a constant value irrespective of a polarization state of input light to the waveguide-type optical diffraction grating.


The station side terminal device of the present disclosure includes: plural terminal devices, each including a buffer section including a through queue and one or more switch queues that temporarily stores packets, and a subscriber side terminal device assignment section that causes unicast packets addressed to switching target subscriber side terminal devices and packets for switching targets that are addressed to all of the subscriber side terminal devices to be stored in a switch queue, and causes unicast packets addressed to non-switching target subscriber side terminal devices and packets for non-switching targets addressed to all of the subscriber side terminal devices to be stored in the through queue; and a terminal device assignment section that transmits obtained unicast packets and obtained packets addressed to all of the subscriber side terminal devices to the terminal device designated by the packets.

Information about usage bandwidths of the ONUs and information about cover areas of the RRHs are acquired. A maximum cover area of each RRH is set. The remaining RRH included in the currently-set cover areas within the maximum cover area of each RRH is identified. The plurality of ONUs, a total usage bandwidth of which is smaller than or equal to an amount of traffic accommodatable by a single ONU, are identified as a sleep candidate ONU group. The ONU and the RRH to be switched to the sleep state are selected. If the maximum cover area of the RRH connected to one of the ONUs included in the sleep candidate ONU group includes a current cover area of the RRH connected to the remaining ONU, the remaining ONU and the RRH connected to them are selected as the ONU and the RRH to be switched to the sleep state.

There is provided an image processing device including: a preprocessing unit configured to perform preprocessing for reducing an amount of information of an input image to generate a preprocessed image and supply the preprocessed image to an encoding processing unit that encodes and outputs the preprocessed image, wherein the preprocessing unit includes a transformation unit configured to divide the input image into predetermined blocks, perform transformation processing with a predetermined method, and generate transform blocks, a block-of-interest determination unit configured to hold region information indicating a region of interest or a non region of interest of the input image and determine whether or not each transform block is a block of interest on the basis of the region information, and an information amount reduction unit.


A PV vector measuring apparatus includes: a light source 101configured to output probe light; a polarization switch 102 that can freely set a state of polarization of input light; a polarimeter 104; a PV-vector calculating device 105; and a rectangular wave generator 106. The polarization switch alternately switches between two orthogonal states of polarization in accordance with a rectangular wave modulation signal output from the rectangular wave generator. Output light from the polarization switch is input to a measurement object 103. The polarimeter 104 measures time dependency of an SOP vector of output light output from the measurement object. The PV-vector calculating device calculates a characteristic vector, which expresses a rate of polarization change in the measurement object, from the time dependency of the SOP vector.
