摘要： The invention provides an optical phase modulator having a substrate made of an electro-optical material, a signal electrode provided on the substrate and first and second ground electrodes provided on both sides of the signal electrode. The electrodes are provided so that a size of the first gap between the first ground electrode and the signal electrode is smaller than a size of a second gap between the second ground electrode and the signal electrode. Furthermore, an optical waveguide is provided in the first gap as an optical phase modulator and not provided in the second gap. A driving voltage required for the phase adjustments is thereby lowered, the impedance matching is easily made and excellent radio frequency property can be realized.

摘要： An optical waveguide is formed on a ferroelectric substrate having a thickness of 20 μm or less by diffusion of a dopant or ion exchange. The optical waveguide has a non-branched section 2a operating on single mode and a pair of branched sections branched from the non-branched section 2a. Each of the branched sections has a connecting part 7 extending from a branching end 10 and a multi mode propagating part 8 continuously formed from the connecting part 7. The multi mode propagating part 8 has a width “m” larger than a width “t” of the non-branched section. A width “p” of the connecting part increases from the non-branched section 2a toward the multi mode propagating part 8.
