Abstract

See full text

An optical modulator includes, a semiconductor substrate, an optical waveguide portion disposed on the semiconductor substrate, a first P-N junction disposed on the semiconductor substrate, and a second P-N disposed on the semiconductor substrate. The optical waveguide portion provides an optical path for light that is to be modulated. The first P-N junction is disposed on the semiconductor substrate along the optical path and defines a border between an N-doped portion disposed on the semiconductor substrate and a P-doped portion disposed on the semiconductor substrate. The second P-N junction is disposed on a portion of the semiconductor substrate alongside the optical path and spaced apart from the first P-N junction.
