IPC: G02F1/313
Filed: 1990-01-23
Abstract: PURPOSE:To solve the problem that the dependency on polarization cannot be eliminated by forming the crystal structure of optical waveguide layers in such a manner that the axis perpendicular to the {110} face is set parallel with the propagation direction of light and a substrate surface and that the angle formed by the axis perpendicular to the {001} face with the perpendicular line of the substrate surface is set at a prescribed angle. CONSTITUTION:When two beams of the polarized light are inputted via an input port 17a or 18a to the waveguide 17 or 18, the electrooptical effect of the same magnitude is generated in the respective beams of the polarized light at the time when two beams of the polarized light pass a coupling region 19. The two beams of the polarized light advance in the same waveguide 17 or 18 and are outputted from an output port 17b or 18b. The same magnitude of the electrooptical effect for two beams of the polarized light are, therefore, obtd. if the direction of the crystal axes is set by setting the angles phi1, theta1 formed by the optical axes of the double refractions of the waveguides 17, 18 and the crystal axes at the prescribed value.
