Title: Electrically induced optical waveguide filter - has periodic electrode structure blocking and passing wavelengths related to unit dimensions
IPC: G02F1/035
Filed: 1973-11-30
Abstract: An electrically induced waveguide designed as an optical filter has a body consisting of an electrooptic crystal transparent for the light waves to be used. A number of spaced electrodes, all on the same face of the crystal, are connected to form a pair of electrodes between with a crystal zone is defined. On application of a specific voltage between the electrodes they function as a waveguide for the light waves concerned. The pairs of electrodes have a geometric structure showing periodicity along the length of the system (58, 59). The elements have a spacing which is an exact multiple of the half-wavelength of the light so as to block the passage of light of a wavelength having a specific relationship to this structure and to transmit light of other wavelengths. The structure may be formed by a number of projections arranged along a pair of parallel parts of the pair of electrodes (55, 56).
