  • Publication number: 20200026066
    Abstract: A spatial light modulator (SLM) having improved &endue, and methods of fabricating and operating the same are described. Generally, the SLM includes pixels each including a tensile membrane suspended over a surface of a substrate by posts at corners thereof. The tensile membrane includes an electrostatically deflectable piston and flexures through which the piston is coupled to the posts. A platform having first light reflective surfaces is supported above and separated from the piston by one or more central posts extending from the piston to the platform, and a face-plate including a second light reflective surface is suspended over the platform. The face-plate includes plurality of apertures through which the first light reflective surfaces are exposed. Electrostatic deflection of the piston brings light reflected from the first light reflective surfaces into constructive or destructive interference with light reflected from the second light reflective surface. Other embodiments are also described.
