Opto-mechanical device

摘要

An opto-mechanical device is constituted by an optically responsive actuating member in which a mechanical strain occurs in response to changes in its illumination. The actuating member is preferably at least partly formed from a semiconducting glassy matrix such as a chalcogenide glass. Preferably the opto-mechanical device illuminates the actuating member with light which is preferably plane polarized. Preferably it also varies the polarization angle of the plane polarized light to cause a change in the strain generated in the actuating member.
