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