Abstract
An optical switch includes an input port, output ports, and a spatial light modulating section that receives an optical signal from the input port to deflect the optical signal to a selected one of the output ports. A phase distribution with the same radius of curvature as that of a wavefront of the optical signal and a phase distribution that allows the deflected optical signal to be coupled to the output port are set for the spatial light modulating section.
