Ra. Becker et Be. Kincaid, RUGGED, LOW-COST PIGTAILING APPROACH FOR LINBO3 INTEGRATED-OPTIC DEVICES, Journal of lightwave technology, 12(1), 1994, pp. 44-48
A new approach for attaching optical fibers to LiNbO3 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-degrees-C
with only +/- 0.5-dB change in optical insertion loss.
