Abstract
An optical switch includes: a semiconductor substrate, including a first rotation part and a first torsion beam disposed at two ends of the first rotation part, where 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; a first latching structure, disposed on a surface of the first torsion beam, the first latching structure including a form self remolding (FSR) material layer and a thermal field source, where 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 form remolding under the thermal field, so as to latch the first rotation part and the microreflector in a position after rotation.
