    摘要: A travelling wave-type optical modulator (1) has a substrate (3) made of an electro-optic material, optical waveguides (6A,6B) fabricated on the top surface of the substrate, and electrodes (2A,2B,2C) for modulating an optical wave through the optical waveguide. The substrate is partially thinned from the bottom surface of the substrate to form a first thinned portion (3f) and a second thinned portion (3e) so that the thickness of the first thinned portion is set to be larger than the thickness of the second thinned portion, and the optical waveguide is positioned in the first thinned portion.

    摘要: A travelling wave-type optical modulator has a supporting substrate (18) and a ferroelectric single crystalline layer (1A) adhered on the supporting substrate with an adhesive layer (3A). The ferroelectric single crystalline layer has thicker parts (5,8) and thinner parts (6) forming at least one ridge within the modulating region of the travelling wave-type optical modulator (20) as viewed in the cross section of the modulating region. Then, an optical waveguide (2) is formed in the thicker part of the ferroelectric single crystalline layer, and electrodes (11,21) for modulation are provided on the thinner part of the ferroelectric single crystalline layer.

    摘要: An optical waveguide element includes a substrate (1) showing electrooptical effects and having a pair of opposite major planes (1A, 1B), an optical waveguide (2) formed on one major plane of the substrate, and an electrode (3) for applying a modulation signal to an optical wave transmitted through said optical waveguide. A portion (5) having a relatively small thickness is formed at a region of the substrate at least positioned correspondingly to the electrode (3), and a buffer layer (6) is formed between the substrate and the electrode. Impedance conformity with the modulation signal applied to the electrode is performed by controlling the thickness of the thin portion (5).
