ABSTRACT:
An optical filter for blocking radiation of preselected wavelength is described which comprises a colloidal suspension of an optical medium and a multiplicity of microspheres of optical dimensions in a substantially regular three-dimensional array, the optical medium and microspheres comprising materials having matched indices of refraction in the absence of incident radiation, but at least one index of which varies nonlinearly with incident electric field whereby an index mismatch and resulting Bragg diffraction within the suspension is produced by incident radiation of the selected wavelength.
