Abstract
We demonstrate that a prism coupling characterization technique can lead to simpler Waveguide Bragg Grating (WBG) designs and easier fabrication by avoiding channel transmission. The experimental results have shown that the incident laser beam’s collimation was maintained after coupling to a planar waveguide with an overall efficiency of 10%.
