Rugged, low-cost pigtailing approach for LiNbO/sub 3/ integrated optic devices

Abstract

A new approach for attaching optical fibers to LiNbO/sub 3/ integrated optic devices is described. The all-solder approach, which uses no organic adhesives, is fast, robust, and low cost. A three-port fiberoptic gyro chip was pigtailed, and temperature cycled from 20 to 100/spl deg/C with only +//spl minus/0.5-dB change in optical insertion loss.< >
