Curvature effects in two-dimensional optical devices inspired by transformation optics

Light transport in curved quasi two-dimensionalwaveguides is considered theoretically. Within transformation optics andtensortheory, a concise description of curvature effects on transverse electric and magnetic waves is derived. We show that the curvature can induce light focusing andphotonic crystal properties, which are confirmed byfinite element simulations. Our results indicate that the curvature is an effective parameter for designing quasi two-dimensional optical devices in the fields of micro and nanophotonics.
