High efficient self-written connection between V-slot optical waveguide

Abstract

In the optical interconnection of board level, 45-degree micro mirrors are used to achieve 90-degree optical path change. These mirrors are often fabricated by using a rotating blade and this method has a serious problem of cutting other waveguides in the vicinity. A self-written waveguide ha been successfully applied to repari and connect these waveguides. So, it will be possible to allow optical signals to be input and output at a specific location on the board.
