Paper Abstract

Bending efficiency of three-dimensional (3-D) horizontal single- and multiple-slot waveguide microrings are analyzed using a combination of effective-index and modified transfer-matrix methods. The effects of waveguide parameters, low-index material, high-index material, asymmetric structure, and asymmetric slots on the bending loss are studied. We show that the bending efficiency can be enhanced by applying asymmetric structures and asymmetric slots. In addition, it is demonstrated that the bending loss increases with increasing the number of slots. However, by using proper thicknesses for different high-index layers of horizontal multiple-slot waveguide, it is possible that horizontal multipleslot waveguide can provide a lower bending loss than the single-slot one.
