Claim Text:
1. An optical module comprising: a waveguide substrate including an optical waveguide and a plurality of electrodes that apply an electronic signal to the optical waveguide; a relay substrate disposed adjacent to the waveguide substrate; a terminal substrate disposed adjacent to the waveguide substrate and opposite to the relay substrate across the waveguide substrate; and a carrier substrate on which the waveguide substrate, the relay substrate, and the terminal substrate are mounted, wherein the plurality of electrodes have a first interconnect unit extending from the relay substrate to the terminal substrate via the waveguide substrate and second interconnect units extending from the first interconnect unit and branching on the terminal substrate, a first interconnect branch among the second interconnect units includes a capacitor and a terminal resistor, and a second interconnect branch among the second interconnect units is connected to an interconnect of the carrier substrate via a bias resistor, passes under the waveguide substrate, and extends to a DC electrode for bias-adjusting on the relay substrate.
