摘要：
A new strategy for radiation loss reduction in curved slab waveguides is presented. The proposed strategy is based on the proper modi. cation of the boundary conditions at the core-to-cladding interface, whereupon extremely thin conductive nanolayers with non-zero surface conductance are imposed. The obtained numerical results show a noticeable decrease in the overall loss level.
