摘要： An optical waveguide element module decreases discontinuity of electrical connection between an optical waveguide element and a relay substrate, without wire-bonding using long wires. An edge shape L of the signal electrode side of the ground electrode is surrounded by two shapes (L1, L2). Shape L1 is obtained by connecting an input end of the control electrode to a location where a space between the ground electrodes becomes W2. Shape L2 is such that an impedance change of the control electrode from the input end to the location at which the space between the ground electrodes becomes W2 is constant or continuously changes. A space between grounding wires connecting the ground electrodes of the element and ground lines of the relay substrate is larger than a space between the ground electrodes. In an embodiment, a terminal substrate and an output end of the control electrode are connected.

摘要： Provided is an optical modulator in which low-voltage drive and a stable modulation characteristic are secured over a wide bandwidth. An optical modulator includes: a substrate 10; an optical waveguide (not shown) formed in the substrate 10; a modulation electrode (a signal electrode 11 and a ground electrode 12) for modulating light waves propagating through the optical waveguide; and an external signal line (not shown, only a connection connector 4 is shown) which is provided outside the substrate and supplies a modulation signal to the modulation electrode, in which an impedance value of the modulation electrode in an active region S in which an electric field formed by the modulation electrode is applied to the optical waveguide is set to be lower than an impedance value of the external signal line, and an impedance adjustment part 21 having an impedance adjustment function with respect to mainly a modulation signal in a low-frequency area and configured of a lumped-constant circuit, and an impedance matching line L having an impedance adjustment function with respect to mainly a modulation signal in a high-frequency area are disposed between the external signal line and the active region of the modulation electrode.
