Abstract
A reflective spatial light modulator (SLM) includes a first substrate, a second substrate and an electro-optic material positioned between the first and second substrates. The first substrate includes a reflective ground layer that acts as a continuous first electrode and the second substrate includes a pixel layer having a plurality of pixel elements formed in a pattern. The pixel elements are formed of a transparent conductive material and are separated by inter-pixel regions formed of a non-conductive material. A transmissivity of the electro-optic material in a vicinity of each of the plurality of pixel elements is controlled by a potential difference applied between the first electrode and a respective one of the pixel elements.
