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.

A method of poling and calibrating electro-optic fibers is disclosed. Metal electrodes are used to utilize the electro-optic effect to impart phase delays to the optical signal. Moreover, one or more electrodes may be used for heating of the device to reach softening temperatures of the electro-optic material, which allows easy, effective and efficient poling of the electro-optic material. A method based on continuous or periodic optical feedback is used to automatically calibrate the electro-optic device when its performance degrades with time to relaxation of molecular orientations.
