A numerical study of the propagation dynamics of ultrashort pulses in a coupled-cavity-type multilayered structure doped with Kerr-type nonlinearity showed that such a structure improves the switching contrast of recently proposed optical-limiting and switching devices consisting of a nonlinear Bragg reflector.

Key words : Bragg reflector, Bragg stop-band gap, nonlinear photonic band system, Kerr-type nonlinearity, gap soliton, nonlinear coupled-cavity-type multilayered structure
