Abstract
The optical device includes a waveguide on a base. The device also includes a modulator on the base. The modulator includes an electro-absorption medium configured to receive a light signal from the waveguide. The modulator also includes field sources for generating an electrical field in the electro-absorption medium. The electro-absorption medium is a medium in which the Franz-Keldysh effect occurs in response to the formation of the electrical field in the electro-absorption medium. The field sources are configured so the electrical field is substantially parallel to the base.
