摘要： It is an object of the invention to provide a light modulator using a thin plate having a thickness of 20 µm or less and capable of stably holding a conductive film suppressing troubles such as resonance phenomenon of microwaves in a substrate and pyro-electric phenomenon and to provide a method of fabricating the light modulator. The light modulator includes: a thin plate (10) formed of a material having an electro-optic effect and having a thickness of 20 µm or less; a light waveguide (11) formed on the front or rear surface of the thin plate; and modulation electrodes (13, 14) formed on the front surface of the thin plate to modulate light passing through the light waveguide. The light modulator further includes a reinforcing plate (16) bonded to the rear surface of the thin plate and a conductive film (17) continuously formed in the range from the side surface of the thin plate to the side surface of the reinforcing plate.

摘要： A method of adjusting the optical axis of an optical waveguide element which can improve a manufacturing yield of the optical waveguide element, an alignment yield between the optical waveguide element and an input waveguide means, etc. and can equalize the branch ratio in a Y-branch waveguide; and an optical waveguide element which can be made compact and also inhibited from complication in structure by using this method. The optical waveguide element (5) formed on a substrate comprises at least a linear waveguide (6) and a Y-branch waveguide (7) branched from the linear waveguide. The method of adjusting the optical axis of the optical waveguide element (5) when connecting the optical waveguide element (5) and an input waveguide means (3) for inputting a light wave into the optical waveguide element (5) is characterized in that a wide band light or two or more single-wavelength lights (light sources (1, 2)) having a different wavelength are inputted into the linear waveguide via the input waveguide means (3) and then the optical axes of the optical waveguide element (5) and input waveguide means (3) are so adjusted that light waves (10, 11) output from individual branch arms (8, 9) of the Y-branch waveguide may have nearly identical light intensity.
