“…For some detuning values the transmission characteristic becomes bistable (see Figure 3), which corresponds to the two different transmission states for the same input peak power 16 . Such bistable behavior can be found also in other types of nonlinear resonators, e.g.…”

We study numerically nonlinear pulse propagation in a phase-shifted Bragg grating with a π phase-shift. The phase-shift acts as a cavity, accumulating the field inside the grating, and hence improving the switching efficiency. Due to material nonlinearity such cavity can operate in a bistable regime, enabling all-optical switching between high and low transmission states. We give optimization criteria for grating design that reduce the switching threshold and minimize the response time of the device. We demonstrate that if the grating and the pulse parameters are chosen carefully, a temporal reshaping of the transmitted pulse occurs. An asymmetric shape of the output pulse is an indication of the pulse self-switching between the two states of a bistable Bragg cavity.

“…Besides, the optical bistability has also been discussed in double cavity systems [45,46] as well as in a composite photonic molecule cavity optomechanical system consisting of two whispering gallery mode microcavities. [47] Optical bistability has many practical applications in the field of nonlinear optics, for example, signal processing, [48] all-optical switching, [49] all-optical transistors, [50] and all-optical sensing elements. [51] Like optical bistability, the four-wave mixing (FWM) intensity process is also a nonlinear effect of the quantum-optical field based on quantum coherence and quantum interference which is frequently studied in the nonlinear optics.…”

We investigate the tunable bistable behavior of a hybrid nano-electro-optomechanical system (NEOMS) composed of S-shaped in the presence of two-level atoms, trapped inside a Fabry–Pérot cavity, and driven by a strong driving field and a weak probe field. The bistable behavior of the steady-state photon number and the mechanical steady-state positions are discussed. Further, we tune bistability by tuning all the coupling frequencies involved in the system and amplitude of the driving field. The present study provides the possibility of realization of a controllable optical switch depending on atom-field coupling, optomechanical coupling, electrostatic Coulomb coupling, and threshold power. In addition, we discuss that the non-linear effect of the hybrid NEOMS generates the four-wave mixing (FWM) process. Moreover, we show that the FWM process can be suppressed by the atom-field detuning and cavity-field detuning, which exhibits low photon transmission.
