Japanese Patent JPS6135524
Kind Code:
B2
Abstract:
A method of fabrication and the resulting structure for a birefringent transmission line having particular application as an optical waveguide. The instant transmission line is fabricated so as to be adapted to maintain the state (e.g. the polarization vector) of polarized electromagnetic radiation propagating therethrough. Birefringence in the instant transmission line is geometrically generated by producing oblong regions having different indices of refraction through a cross-section of the transmission line. A preferred technique by which to generate birefringence includes the method step of bombarding the transmission line with a supply of atomic particules, such as energetic hydrogen ions, whereby to implant a damaged region of oblong cross-section and thereby cause an internal swelling therein. By way of a preferred example, the transmission line herein described may be a single-mode optical fiber.
