ABSTRACT:
A piezoelectric optical relay is disclosed in which a solid slug moves within a switching channel formed in relay housing. An optical path passing through the switching channel is blocked or unblocked by motion of the solid slug. Motion of the solid slug is controlled by at least two piezoelectric actuators within the switching channel. Motion of the solid slug is resisted by a liquid, such as a liquid metal, that wets between the solid slug and at least one fixed contact pad in the switching channel. The surface tension of the liquid provides a latching mechanism for the relay.
