摘要： An optical modulator is provided with an optical waveguide including an input-side single-mode waveguide for propagating inputted light at single mode, a multi-mode waveguide for propagating the light propagated from the input-side single-mode waveguide at plural guided modes, and an output-side single-mode waveguide for propagating the light propagated from the multi-mode waveguide at single mode to output the light. A lower electrode layer is disposed below the multi-mode waveguide, and an upper electrode is disposed above the multi-mode waveguide.

A phase of each of the guided modes propagating through the multi-mode waveguide is modulated by applying an electric field to the multi-mode waveguide, and intensity of the light outputted from the output-side single-mode waveguide is modulated by an interference of the phase-modulated guided modes.

摘要： In an optical waveguide device, a laser beam is collected to an end face of a channel waveguide, and introduced into a PLZT thin film optical waveguide. The incident laser beam, when emitted from the channel waveguide, diverges in the PLZT waveguide, permeates a thin film lens and is collimated into 0.4 Mm size. When a high frequency voltage is not applied to a comb Al electrode, the laser beam is collected after penetrating through the second thin film and emitted from the end face through the channel waveguide to form an emission beam. When the high frequency voltage is applied to the comb Al electrode, a diffraction grating is formed by an acousto-optic effect, and the laser beam is deflected. The deflected laser beam, when penetrating through the second thin film lens, is collected and emitted from the end face through the channel waveguide in adjacent with the above-described channel waveguide to form a deflected emission beam.
