Abstract: An optical modulator includes: an optical waveguide element including an optical waveguide formed on a substrate and a signal electrode for controlling a light wave propagating through the optical waveguide; a drive circuit for outputting two high-frequency signals; and two terminating resistors for respectively terminating outputs of the two high-frequency signals from the drive circuit. The output of one of the high-frequency signals of the drive circuit propagates through the signal electrode of the optical waveguide element and is terminated by a first terminating resistor which is one of the terminating resistors. The output of the other of the high-frequency signals of the drive circuit is terminated by a second terminating resistor which is the other of the terminating resistors. A resistance value of the second terminating resistor is greater than a resistance value of the first terminating resistor.

Abstract: A dispersion liquid contains a metal oxide particle surface-modified with a silane compound and a silicone compound, when a transmission spectrum of the metal oxide particles that are obtained by vacuum-drying the dispersion liquid is measured in a wavenumber range of 800 cm−1 or more and 3800 cm−1 or less with FT-IR, IA/IB≤3.5 is satisfied (IA is a spectrum value at 3,500 cm−1 and IB is a spectrum value at 1,100 cm−1), and, when the dispersion liquid and methyl phenyl silicone are mixed such that a mass ratio of a total mass of the metal oxide particles and the surface-modifying material to a mass of methyl phenyl silicone becomes 30:70 and the hydrophobic solvent is removed, a viscosity is 9 Pa·s or less.

Abstract: An optical modulator includes a relay substrate having signal conductor patterns that connect signal input terminals and signal electrodes of an optical modulation element and ground conductor patterns, and a housing, in which the signal conductor pattern includes a component mounting portion including an electrical circuit element. Two ground conductor patterns sandwiching the signal conductor pattern are formed in an asymmetrical shape in a plan view within a component mounting area having a square shape in the plan view centered on the component mounting portion. A direction of a side of the component mounting area having the square shape is same as the extending direction of the signal conductor pattern and a length of a side of the component mounting area is equal to a distance from a center of the component mounting portion to a portion on an adjacent signal conductor pattern closest to the center.
