OPTICAL TAPS FOR CIRCUIT BOARD-MOUNTED OPTICAL WAVEGUIDES

摘要

A method for installing an optical tap into an optical waveguide formed in a printed circuit board which comprises obtaining a printed circuit board having an optical waveguide formed therein, cutting a transverse groove that has a front plane and a back plane into the optical waveguide, such that the back plane of the groove forms an oblique angle relative to the incident beam of light, and inserting a pre-fabricated beamsplitter into the groove so that the beamsplitter is positioned at the oblique angle of incidence relative to the beam of light to enable a predetermined portion of the beam of light to be directed out of the waveguide.
