M-type electrode planar guided-wave beam splitter
A planar guided-waved beam splitter with an M-type electrode is proposed, analysed and demonstrated. The device was realised on a Ti-diffused LiNbO3 planar waveguide and tested under a 6328 Å optical wave. It exhibited a deflection power 1.38 times higher than that of a zig-zag array beam splitter.
