Abstract
A polymer modulator includes a first cladding layer, a passive core region with a surface abutting a surface of the first cladding layer, the passive core region extending to define an optical input and an optical output for the modulator, a shaped electro-optic polymer active component with a surface abutting a surface of a central portion of the passive core region, the shaped electro-optic polymer active component being polled to align dipoles and promote modulation of light, the shaped electro-optic polymer active component having a length that extends only within a modulation area defined by modulation electrodes, and a second cladding layer enclosing the shaped electro-optic polymer active component and designed to produce adiabatic transition of light waves traveling in the passive core region into the shaped electro-optic polymer active component to travel the length of the shaped electro-optic polymer active component and return to the passive core region.
