Abstract:
A thermoelectric microactuator on a substrate, the microactuator comprising:a first temperature control element having a first surface bonded to the substrate and having a second surface; a first electrically nonconductive layer having a first surface bonded to the second surface of the first temperature control element, and having a second surface; and an actuator arm, the actuator arm comprising: a first region bonded to the second surface of the first nonconductive layer; a flexure contiguously extending from the first region to an end cantilevered beyond the first nonconductive layer and forming an axis at the junction of the flexure and the first region, wherein the first temperature control element controls the temperature of the actuator arm to thereby deflect the flexure about the axis; and a reflective surface configured to reflect an incident light wave.
