Abstract

The Y-branch waveguide is one of the basic components of optical circuits in the network and computer devices. Considering the high-density integration of optical circuits, a wide angle Y-branch waveguide, which is a small waveguide, is highly desired. Authors had been prosed a new Y-branch waveguide with reflecting surface to achieve low- los and wide branch angel> Also we had shown the successful results of low-loss characteristics and the large tolerance to the fabrication error by numerical analyses. In this paper, we evaluate the loss characteristic and the stability of branching ratio of proposed Y-branch optical waveguide with reflecting surface from experimental results. The proposed model is fabricated by UV-curing method and PMMA resin because of its transparency and ease of fabrication. In these experiments, successful results, such as low-loss, wide-angle abilities and availability of variable branching ratio were obtained. In all experiment and numerical analyses, we assume that the multi-mode waveguide is used in optical circuits considering the optimum connections to the VCSEL.
