The system and the taper guided wave road and the production method in order to improve the optical coupling efficiency with the optical fiber and one somatotype plane surface guided wave road

摘要

SolutionsThe taper guided wave road optical mode transmitter (20), plane surface baseplate structure (16) the taper core which was formed on is included. The core (21) in order to attach the taper of vertical direction, step (22) is etched in the surface of the core. The step in order optical mode quality of the optical fiber of desire to convert to the optical mode quality of the plane surface guided wave road of desire alongside the optical axis of the taper guided wave road, has with depth and the length which are selected. As for the core, it can be able to attach the taper to horizontal direction in order to form two dimensional taper guided wave road. As for the taper guided wave road, the plane surface light wave circuit which makes optical coupling loss decrease with the optical fiber and the PLC guided wave road (PLC) it is possible to be included in one body.
