    摘要: The discloser provides a multi-input and multi-output optical switch capable of switching over all WDM wavelengths. An optical switch according to one embodiment includes: an optical demultiplexing element (3) that demultiplexes an optical signal from at least one input port into individual wavelengths; a first optical deflection element (5), which deflects an incident optical signal, that deflects the wavelength-separated optical signal incoming from the optical demultiplexing element to change a traveling direction for each wavelength to a switch axis direction perpendicular to a wavelength dispersion axis direction; a second optical deflection element (8) that deflects the optical signal incoming from the first optical deflection element to change the traveling direction to the switch axis direction for output to at least one of the output ports; and an optical multiplexing element (10) that multiplexes the optical signal with the different wavelengths incoming from the second optical deflection element.

    摘要: A waveguide type optical switch that can reduce the number of intersections in a matrix optical switch having the configuration of connecting unit optical switches and optical combining devices or optical branching devices to have a connecting function from “multiple inputs to one output” to “one input to multiple outputs”. To reduce the number of intersections in an entire matrix optical switch, an optical combining device of M inputs and one output is divided into (M−1) pieces of unit optical combining elements each having two inputs and one output, which are arranged immediately after (N−1) pieces of respective output ports excluding one piece of the output port closer to the input in the matrix optical switch out of N pieces of the output ports in the optical switch of one input and N outputs.
