摘要： A low-cost fabrication technique, readily extensible to volume manufacturing is presented for 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, and ends of the fiber unaffected by the fabrication and available for splicing with additional fiber sections. The technique is readily adaptable to specialized electrode structures including striplines and/or microstrip lines for high frequency applications and segmented electrodes for quasi-phasematched three-wave mixing applications. By combining the electrooptically active fiber segment with other fibers in an integrated fiber modulator, high frequency modulation of an optical signal may be achieved with applications in telecommunications. By including a Bragg grating structure in the same fiber segment, a remotely accessible electric field sensor is achieved. Three-wave mixing processes in the electrooptically active fiber segment will allow the generation of additional coherent radiation sources in both the visible/UV and infrared spectral ranges.
