Abstract

Connection between optical active/passive elements and libers is very important in practical device packaging. Multichannel connection is very hard if we use liber array direct coupling to multichannel elements such as laser diode arrays, matrix switches, and grating filters. Minford et al. reported a Ti:LiNbO3 seven-channel waveguide concentrator between a single-mode fiber array and a grating filter with a GRIN lens.1 However, Ti:LINbO3 has a relatively low ΔN and needs a large bending radius and connection length to expand the interchannel distance with low insertion loss. To realize compact connecting circuits, a large ΔN waveguide is needed.
