Abstract

An approach to designing very-low-loss, wide-angle Y-junctions for dielectric waveguides is proposed. By introducing two interface planes with properly chosen parameters in the branching region, the conditions for a close (phase) match between the incident field and a desired output distribution suitable for minimal junction scattering are realized. An accurate and numerically efficient method for analysis and design of the proposed structure is described. Numerical results for some sample designs along with a set of simple design criteria are discussed
