Claim 13:
14. An optical transceiver comprising:
an optical transmitter circuit; and
an optical receiver circuit,
wherein the optical transmitter circuit has an optical device comprising a substrate, a layered structure provided on the substrate and including an intermediate layer, an optical waveguide formed of a thin crystal film having an electro-optic effect, and a buffer layer stacked in this order, and an electrode provided on or above the buffer layer and configured to apply a direct current voltage to the optical waveguide, and
wherein a resistivity of the intermediate layer is higher than a resistivity of the buffer layer, and the resistivity of the intermediate layer is higher than a resistivity of the optical waveguide formed of the thin crystal film.
