Abstract
An optical diffuser includes optically anisotropic molecules arranged in a predefined configuration such that the optical diffuser diffuses first light having a first polarization and transmits second light having a second polarization that is different from the first polarization upon receiving the second light. In addition to polarization selectivity, the optical diffuser may also exhibit wavelength selectivity and/or incident angle selectivity. A method of diffusing light using the optical diffuser and a method of making the optical diffuser are also disclosed.
