Patent ID: 7161726

Claim:
A device, comprising: a. a first polymer optical waveguide comprising a bottom crosslinked polymer clad, an electro-optic polymer core, and a top crosslinked polymer clad, wherein the bottom crosslinked polymer clad has a thickness of 2.5–3.5 micrometers, the electro-optic polymer core has a thickness of 2–3 micrometers, and the top crosslinked polymer clad has a thickness of 2.5–3.5 micrometers; b. a second polymer optical waveguide comprising a bottom crosslinked polymer clad, an electro-optic polymer core, and a top crosslinked polymer clad, wherein the bottom crosslinked polymer clad has a thickness of 2.5–3.5 micrometers, the electro-optic polymer core has a thickness of 2–3 micrometers, and the top crosslinked polymer clad has a thickness of 2.5–3.5 micrometers; c. an optical coupling region including the first and second optical waveguides, the optical coupling region characterized as having at least one coupling length and comprising a first bias section, a modulation section, and a second bias section arranged such that light propagates serially through the first bias section, the modulation section, and the second bias section; d. a first bias electrode for biasing the first bias section; e. a modulating electrode for applying a modulating voltage to the modulation section, the modulating electrode being positioned to control the refractive index of the first optical waveguide; and f. a second bias electrode for biasing the second bias section.
