A Thermally Poled Electrooptic Fiber

We have reported1 previously on a planarized fiber-poling structure which allows us to apply a high field across a polished fiber and results in a linear electrooptic coefficient as high as 0.3 pm/V using a commercially available D-fiber. This fabrication technique has several advantages including: low cost volume manufacturing capability; planar structure to allow lithographic definition of high-speed circuits; and fiber ends unaffected by the processing to provide low-cost packaging and integration with fiber systems.
