Abstract:
1. A semiconductor optical device comprising: a semiconductor substrate; an electro-absorption modulator and at least one optical device being monolithically integrated and arranged on the semiconductor substrate; an insulative layer surrounding the electro-absorption modulator and the at least one optical device arranged on the semiconductor substrate; at least two metallic pads, one of which being an electrode of the modulator, that are formed at a distance from each other on the insulative layer; a plurality of metallic wires electrically connecting the electro-absorption modulator to the metallic pads and adapted for adjusting an amount of inductance of the electro-absorption modulator, the metallic wires being formed on the insulative layer; and a dielectric layer adapted for minimizing parasitic capacitance generated in the at least two metallic pads and the plurality of metallic wires, said dielectric layer being formed under an upper portion of the insulative layer in which the at least two metallic pads and the metallic wires are arranged.
