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.
Claims6
An integrated optics polarization conversion device comprising a flat substrate made from a uniaxial crystalline material having electro-optical properties and a guide structure with given optical axis formed by doping the material of the substrate and in which at least two separate modes may propagate, wherein said crystalline material has an optical axis contained in a plane perpendicular to the substrate and parallel to the axis of one guide, and forming an angle with the plane of the substrate less than (.pi./2) radians.
