    Abstract

    We have implemented a new grating-type spatial optical reflection switch based on phase change material (PCM) for usage at optical communication wavelength. This grating device switches on/off the light or steers the light propagation direction by switching the PCM grating between its amorphous and crystalline states. Thus, the switching status is non-volatile and the device is promising for power saving optical network. Based on the design by numerical computations, the prototype grating device was fabricated by electron beam lithography and laser interference lithography techniques. The static switching characteristics were measured by optical diffraction experiments for the two states of the grating.
