Abstract

See full text

An optical device includes an optical modulator on an optical IC chip. The optical modulator includes an optical waveguide, first and second wiring patterns that are formed along the optical waveguide and a polymer pattern. A portion of the polymer pattern is formed on the optical waveguide and located in a region between the first and second wiring patterns. Each of the first and second wiring patterns includes a modulation portion that is formed parallel to the optical waveguide, a pad portion, and a transition portion that connects the modulation portion and the pad portion. A shape of a region between the transition portion of the first wiring pattern and the transition portion of the second wiring pattern is a curve. The polymer pattern has a curved portion in the region between the transition portion of the first wiring pattern and the transition portion of the second wiring pattern.
