SUMITOMO OSAKA CEMENT CO....

1. An optical modulator comprising;a substrate having an electro-optic effect;
an optical waveguide formed on the substrate; and
a control electrode for controlling light waves propagating through the optical waveguide,
wherein the optical waveguide has at least two Mach-Zehnder type optical waveguides disposed side by side with each other,
the control electrode has a DC electrode which applies DC bias to the optical waveguide,
a feeder electrode which feeds DC bias to the DC electrode crosses one of two branched waveguides of one of the two Mach-Zehnder type optical waveguides,
a first dummy electrode which neither applies DC bias to the optical waveguide as the DC electrode nor feeds DC bias to the DC electrode as the feeder electrode is provided at a specific position on the other one of the two branched waveguides, which is a specific position symmetrical in relation to a position at which the feeder electrode crosses the one of the two branched waveguides,
a part of the one of the two Mach-Zehnder type optical waveguides is crossed by the feeder electrode and the first dummy electrode, and
a second dummy electrode which neither applies DC bias to the optical waveguide as the DC electrode nor feeds DC bias to the DC electrode as the feeder electrode is provided at a specific position on the other one of the two Mach-Zehnder type optical waveguides, which is a specific position symmetrical in relation to a position at which the feeder electrode and the first dummy electrode cross the one of the two Mach-Zehnder type optical waveguides.

OPTICAL MODULATOR AND OPTICAL TRANSMISSION DEVICE USING OPTICAL MODULATOR

SUMITOMO OSAKA CEMENT CO....

1. An optical modulator comprising:a substrate having an electro-optic effect;
an optical waveguide that is formed on the substrate;
a plurality of bias electrodes each of which controls an optical wave that propagates through the optical waveguide; and
a plurality of photo detectors each of which is disposed on the substrate, and monitors an optical signal that propagates through the optical waveguide,
wherein the plurality of bias electrodes and the plurality of photo detectors are disposed on a same surface of the substrate, and
wherein at least one suppressing unit, which suppresses a surface acoustic wave that propagates from the bias electrode to the photo detector, is entirely disposed between a region in which the bias electrode is formed and a portion in which the photo detector is disposed on the substrate.
