Low-loss multiple-branching circuit in Ti-indiffused LiNbO(3)channel waveguides.
In this Letter we report on a single-mode five-way branching circuit that utilizes a new single-mode three-guide fork as well as coherently coupled bends to achieve approximately 80% optical transmission. The splitting ratios of the three-guide fork are measured for a variety of angles and are compared with theoretical results obtained with a coupledmode analysis.
