The present disclosure relates to wavelength selective switches. In one embodiment, a wavelength selective switch may include a liquid crystal (LC)-based attenuation switching device that has an LC switching module to switch an incident beam to one of a plurality of output paths. The LC switching module may include one or more LC switching cells. The LC-based attenuation switching device further includes a mirror to reflect the beam from the LC switching module so as to output the beam through a corresponding output port, and a temperature compensation module provided on a side of the mirror opposite to the LC switching module. The temperature compensation module may be configured to alter curvature of the mirror as temperature changes so as to compensate for deformation of the LC switching cells due to the temperature change.
