A New Put-in Micro-connector-II Using GRIN Microlenses

For the realization of future large-scale optical fiber communication systems, one of the most important issues is the light coupling between optical fibers and optical components, e.g., semiconductor lasers, OEIC’s, optical waveguides, and optical couplers. However, the individual alignment of optical components for high efficiency optical coupling needs precise adjustment, and several authors have reported on integrated couplers [1] [2]. However, most of them still require some level of precise alignment.
