Abstract

We report on the design and simulation of a novel Silicon-On-Insulator waveguide structures which when excited with TM guided light, emit TE polarized radiation with controlled radiation characteristics[1]. The structures utilize parallel leaky waveguides of specific separations. The structures are simulated using a full-vector mode-matching approach which allows visualisation of the evolution of the propagating and radiating fields over the length of the waveguide structure. It is shown that radiation can be resonantly enhanced or suppressed in different directions depending on the choice of the phase of the excitation of the waveguide components. Steps toward practical demonstration are identified.
