Description: Our analysis shows an unbalanced structure performs better in reflected intensity limiting, while a balanced structure performs better in transmitted intensity limiting. Based on the tradeoff between nonlinear grating strength and saturable absorption, we discover that there exists an optimum saturable absorption coefficient for maximum transmittance, reflectance and pulse compression for a given built-in grating structure (i.e. no linear grating, out-of-phase grating). We show pulse compression up to 50% and pulse stretching up to 20%.We present the first time-domain analysis of Gaussian pulse propagation through resonant nonlinear periodic structures with balanced and unbalanced nonlinear coefficients. The transmission and reflection propagation dynamics are thoroughly analyzed with varying nonlinear and linear grating strengths, pulse width, input intensity, saturable absorption, device length, and carrier lifetime for single and multiple pulses.
