Claim 19:
20. A method of diffusing light, the method comprising:
receiving incident light at an optical diffuser including optically anisotropic molecules arranged in a predefined configuration, wherein the optically anisotropic molecules are arranged in a plurality of domains, each of the plurality of domains including a portion of the optically anisotropic molecules forming a grating-like pattern, and portions of optically anisotropic molecules in adjacent domains are configured to diffract light in different directions;
outputting diffuse light from the optical diffuser in response to receiving the incident light when the incident light has a first set of properties, wherein the first set of properties includes a first polarization; and
transmitting the incident light in response to receiving the incident light when the incident light has a second set of properties, wherein the second set of properties includes a second polarization that is different from the first polarization.
