Abstract
The transmission properties of a one-dimensional grating with a Kerr nonlinearity, at operating frequencies close to the upper edge of the stop-band, have been investigated using the Finite Difference Time Domain (FD-TD) technique. Results show that the structure exhibits a bistable behavior: transitions from strong reflection to nonlinearity-induced transparency and viceversa are found, leading to high-intensity field localization within the grating. In the limit of shallow gratings, FD-TD results are in good agreement with those based on coupled-mode theory (CMT).
