摘要：
An optical switch with a flat transmission property is provided. The optical switch includes an input port, an output port, a diffractive grating configured to perform wavelength demultiplexing on an optical signal from the input port, and LCOS configured to deflect the wavelength-demultiplexed optical signal to the output port. The diffractive grating is pre-arranged such that a shape of the optical signal as entering the LCOS is asymmetric with respect to an axis in the LCOS surface that is orthogonal to a wavelength axis of the diffractive grating.
