摘要： The optical modulator includes optical modulation units. The plurality of optical modulation units is disposed in parallel on the same substrate. One input waveguide branches off to be connected to the Mach-Zehnder type optical waveguide of each optical modulation unit, and an entire optical waveguide is formed such that outputs from the Mach-Zehnder type optical waveguides are combined and output through one output waveguide. A modulation signal with the same intensity is applied to a modulation electrode of each optical modulation unit. In at least some of the optical modulation units, mechanical structures including the modulation electrodes of the optical modulation units are configured such that an amplitude value of an optical output modulated by the modulation signal of the optical modulation unit is ½n (n is a natural number) of a maximum amplitude value in other optical modulation units.

摘要： The purpose is to provide an optical waveguide element module which is to prevent deterioration of electric characteristics by decreasing discontinuity of electrical connection between an optical waveguide element and a connecting substrate (a relay substrate or a terminal substrate) without wire-bonding using long wires. An edge shape L of the signal electrode side of the ground electrode is set to be, in case of a plane view, located in an area surrounded by two shapes (L1, L2) of a shape L1 obtained by connecting an input end or an output end of a coordination x1 to a location at which a space between the ground electrodes becomes W2 using a straight line and a shape L2 of the edge which is constituted so that an impedance change of the control electrode (a signal electrode and ground electrodes) from the input end or the output end to the location at which the space between the ground electrodes becomes W2 is constant or continuously changes, and, furthermore, grounding wires which connect the optical waveguide element and the connecting substrate has a space between the grounding wires connected to the control electrode are larger than a space W1 between the ground electrodes.
