Paper Abstract

It is shown that an interaction of ultrashort optical pulse with a deep modulated 1D periodic structure with cubic nonlinearity is followed either by an optical switching, compression or reshaping of a reflected pulse depending on its duration, intensity and detuning of a carrier frequency from an edge of a forbidden gap. It is found out that a gap structure with a metal cover on a back edge possesses a considerably smaller intensity threshold to attain a compression at pulse reflection.
