Effect of a Subwavelength Layer on All Optical-Diode Action in 1d Photonic Crystal

Abstract: In this paper, the effect of a subwavelength layer thickness with positive-refractive index material on all-optical diode action in a one-dimensional photonic crystal structure is investigated. An asymmetric multilayer stack composed of Kerr-type nonlinear and linear dielectric media and a subwavelength layer is considered. Behaviour of the linear transmission defect mode and nonlinear optical bistabilities for normal incidence of wave to 1D photonic crystal structure from left and right sides are studied. It … Show more

“…The realization of nonreciprocal or symmetry breaking in light transmission is an essential property for communication and information processing in an all-optical domain. Various efforts have been made for achieving asymmetrical light propagation in the past. Most of these structures are complex and requires high electric/magnetic fields to achieve nonreciprocal transmission, questioning the feasibility of their on-chip integration. However, the nonreciprocity in light propagation in the nonlinear regime can be attained by cascading materials with dissimilar nonlinear absorption coefficients.…”

“…In the normal incident case, the characteristics of the PBGs and defect modes, closely depend on the optical properties of the constituted layers and defect layer. The existence of the PBG and defect modes in the optical spectrum (Reflectance, Absorptance or Transmittance) of the PC have leaded to many interesting phenomena and numerous applications of PCs in improving the performance of optoelectronic and microwave devices such as high-efficiency semiconductor lasers, light emitting diodes, wave guides, high-Q resonators, antennas, all-optical diodes and filters, frequency selective surface, optical limiters and amplifiers [13][14][15][16].…”
