Abstract

A waveguide structure capable of aggressive bends (r00) and long-range propagation (1.2dBmm) is described here. The structure uses a step-index slab to create the vertical confinement and a pair of metallic parallel plates on either side of the core for lateral confinement. The parallel plates are dimensioned to ensure that all modes that would cause radiation loss in a bend are cut off.
