Described herein is a method () of forming a spatial light modulator device (). The method () comprises, at step (), providing a planar silicon substrate. At step (), a patternable material () is deposited onto a bonding surface () of the silicon substrate (). At step (), the patternable material () is formed into a predefined patterned structure on the bonding surface (). At step (), an upper layer substrate () is applied to the predefined patterned structure. At step (), a bonding process is performed such that the predefined patterned structure forms a hermetic seal between the silicon substrate () and the upper layer substrate (), defining a cavity between the silicon substrate () and the upper layer substrate () to contain a light modulating material ().

Method of forming a spatial light modulator

Described herein are embodiments of a diffractive optical element () such as a grism. In one embodiment, the diffractive optical element () includes an input surface () configured to receive an input optical signal (), a diffractive surface () adapted to spatially disperse the input optical beam () into a dispersed signal and an output surface () configured to output the dispersed signal from the diffractive optical element. The input surface () and the diffractive surface () are non-parallel and the diffractive surface () is formed in situ by a photolithographic technique.
