Abstract
A simple fabrication technique, readily extensible to volume manufacturing, is presented to produce an electrooptically active fiber segment that can be simply integrated into optoelectronic devices. The fabrication technique offers a dielectric isolation structure surrounding the fiber to allow high field poling, a pair of electrodes used both for poling and for inducing an electrooptic effect that can be lithographically defined for either velocity-matched, high speed RF modulation or quasiphasematched three-wave mixing interactions, and ends of the fiber unaffected by the fabrication and available for splicing with additional fiber sections. An electrooptic coefficient, including overlap between the nonlinearity and the fiber mode, as high as 0.3 pm/V was obtained by combined temperature/electric field poling.
