Light propagation in asymmetric Kerr-nonlinear multilayers with perfect transmission
resonances is theoretically investigated. It is found that hybrid Fabry-Perot-resonator …

The theory of phase-shifted nonlinear periodic structures operating in the stationary regime
is presented. The transmissive properties of the structure are analyzed by solution of the …

The absorption behaviors of a photonic nonlinear (NL) Kerr multilayer doped by a 30 nm-Ge

In our previous study, the refractive indices of freestanding porous silicon (PS) layers were
derived using the envelope method, where the computation is based on the values of local …

We study the optical bistability (OB) in photonic multilayers doped by graphene sheets,
stacking two Bragg reflectors with a defect layer between the reflectors. OB stems from the …

The optical bistability and multistability in one-dimensional photonic crystal with the periodic

The optical bistability based on an asymmetric dielectric Bragg reflector (DBR)–graphene–
DBR (ADGD) structure is investigated numerically in terahertz frequencies. The threshold of …

We investigate the optical bistability of graphene in parity-time-symmetric (PT-symmetric)
photonic lattices incorporated with a defect at terahertz frequencies. The field localization of …
