Abstract

The diffraction from a second-order corrugated waveguide is analyzed to determine its efficiency as an element to redirect a guided wave. Using a rectangular grating, the efficiency is evaluated in an approximate closed form. The dependence upon grating thickness, waveguide thickness, and wavelength are investigated and the results indicate usefulness as a simulation tool for photonic integrated circuits
