A monolithic PIC including a monolithic laser formed in/on a platform and a polymer modulator monolithically built onto the platform and optically coupled to the laser. The modulator includes a first cladding layer, a passive core region with a surface abutting a surface of the first cladding layer, the core region extending to define an input and an output for the modulator. A shaped electro-optic polymer active component has a surface abutting a surface of a central portion of the core region. The active component is polled to align dipoles and promote modulation of light and has a length that extends only within a modulation area defined by modulation electrodes. A second cladding layer encloses the active component and is designed to produce adiabatic transition of light waves traveling in the core region into the active component to travel the length thereof and return to the core region.

Active region-less polymer modulator integrated on a common PIC platform and method

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.

Direct drive region-less polymer modulator methods of fabricating and materials therefor

A hybrid EO polymer/sol-gel modulator in which the sol-gel core waveguide does not lie below the active EO polymer waveguide increases the higher electric field/optical field overlap factor &#x393; and reduces inter-electrode separation d thereby lowering the modulator's half-wave drive voltage V&#x3c0;, reducing insertion loss and improving extinction.
