摘要： An optical polarizer includes a dielectric substrate and a number of elongated dielectric ridges positioned or disposed in spaced relation on a surface of the substrate. Each dielectric ridge has a length direction, curved or straight, that extends along the surface of the substrate. Each dielectric ridge also includes a pair of spaced sides that extend away from the surface of the substrate and a top extending between the spaced sides opposite the surface of the substrate. Each side of each dielectric ridge includes an electrically conductive coating.

摘要： An optical isolator includes a polarizer for receiving an optical signal from an optical signal source, a Faraday rotator disposed on one surface of the polarizer for rotating a polarization of the optical signal output by the polarizer and outputting the same as a rotator output optical signal, and an analyzer disposed on an opposing surface of the polarizer for receiving the rotator output optical signal and for outputting at least a part thereof. The polarizer and the analyzer each include a number of spaced elongated dielectric ridges. Each dielectric ridge has a length direction extending along the one surface of the Faraday rotator, pair of spaced sides that extend away from the one surface of the Faraday rotator and a top extending between the spaced sides opposite the one surface of the Faraday rotator. Each dielectric ridge includes an electrically conductive coating on each side of the dielectric ridge.
