Abstract A microelectromechanical system (MEMS) actuator device includes a substrate; a shape memory alloy over the substrate; and a reflective coating on the shape memory alloy. The shape memory alloy and the reflective coating form a bi-layer cantilever beam having a first end anchored to the substrate, and a second end released from the substrate. The second end of the cantilever beam articulates between a deflection configuration away from the substrate and a non-deflection configuration towards the substrate based on a thermal phase change in the shape memory alloy.
