  • Integrated optics device for optical polarization conversion
    Patent number: 4732444
    Abstract: An integrated optics optical polarization conversion device comprising a guide structure formed by integrated optics in a flat substrate made from a uniaxial crystalline material having electro-optical properties in which two distinct modes may propagate. In accordance with the invention, the optical axis of the crystal of said substrate forms an angle with the plane of the substrate less than (.pi./2) radians. In one of the variants, said axis is parallel to the direction of propagation of the guided wave and the device comprises a single set of homogeneous electrodes.
