摘要: The present invention provides an optical signal processing device with a transponder aggregator function by which theoretical loss is not increased even if the number of necessary transponders is increased. Optical signals inputted from input ports are inputted to a PLC. The PLC has SBTs. The input ports are connected to the input-end SBT, and a plane wave is outputted from an output end of the PLC to the space side at an angle different for each input port. Optical signals outputted by the PLC are changed in their optical paths on the x-z plane by a cylindrical lens (Lsp) designed to refract optical signals in the x-axis direction, and are reflected by an LCOS at different regions corresponding to the positions of the input port. The reflected optical signals are incident on the output-end SBTs on the PLC, and are outputted to output ports via demultiplex parts.
