Abstract:
1. An optical switch, comprising: a semiconductor substrate, comprising a first rotation part and a first torsion beam disposed at two ends of the first rotation part, wherein the first torsion beam is configured to drive the first rotation part to rotate; a microreflector, disposed on a surface of the first rotation part of the semiconductor substrate; and a first latching structure, disposed on the first torsion beam, the first latching structure comprising a form self remolding (FSR) material layer and a thermal field source, wherein the thermal field source is configured to provide a thermal field for the FSR material layer, and the FSR material layer is configured to undergo foam remolding under the thermal field, so as to latch the first rotation part and the microreflector in a position after rotation; wherein the FSR material layer comprises a material configured to change from a solid to a liquid under the thermal field provided by the thermal field source, and the liquid undergoes form remolding under excitation of the first torsion beam and solidifies into the solid again after the thermal field is removed.
