Abstract:
An in-line fiber-optic polarizer comprising:a pair of optical fiber core portions aligning along an optical axis, each one of said pair of optical fiber core portions defining a respective one of a confronting pair of end surfaces angulated with respect to said optical axis at substantially the compliment of a Brewster angle; a dielectric layer disposed between said pair of end surfaces and being in contact with each one of said pair of end surfaces, said dielectric layer including plural sub-layers integral with one another, said plural sub-layers including high-index sub-layers each adjacent to a respective one of said pair of end surfaces, and at least one low-index sub-layer disposed between said high-index sub-layers, each of said high-index and low-index sub-layers having a respective index of refraction determining said Brewster angle; further including a pair of ferrules each holding a respective one of said pair of optical fiber core portions, and wherein each of said pair of ferrules defines a respective one of a pair of end faces each parallel and coextensive with a respective one of said pair of end surfaces; and wherein one of said pair of end faces bonds with and carries said dielectric layer, and said dielectric layer spans said end surface of the respective one of said pair of optical fiber portions which is parallel and coextensive with said one end face.
