Thermo-optic effect induced tunable phase controlled propagation of solitons in a Jaynes-Cummings-Hubbard model.

The manipulation of light propagation has garnered significant attention in discrete periodic photon structures. In this study, we investigate the impact of an adjustable phase on soliton behavior within a one-dimensional (1D) coupled cavity array. Each cavity is doped with two-level qubits, and the system can be effectively described by a Jaynes-Cummings-Hubbard model (JC-Hubbard model).

Bogoliubov polaritons mediated strong indirect interaction between distant whispering-gallery-mode resonators.

We propose a method to achieve a strong indirect interaction between two distant whispering-gallery-mode (WGM) resonators in a hybrid quantum system at room temperature, even when the distance between them exceeds 40 wavelengths. By exploiting the quantum critical point, we can greatly enhance both the effective damping rate and the coupling strengths between a WGM resonator and a low-frequency polariton. We introduce a large effective frequency detuning to suppress the effective damping rate while maintaining the enhanced coupling strength.

Thermo-optomechanically induced optical frequency comb in a whispering-gallery-mode resonator.

We present a theoretical study that combines thermal and optomechanical effects to investigate their influences on the formation of the optical frequency comb (OFC) in whispering-gallery-mode (WGM) microcavities. The results show that the cut-off order and center frequency of OFC affected by thermal effects exhibit an overall redshift by varying the power and detuning of the pump field, which provides the possibility of tuning the offset frequency of OFC. Our study demonstrates a method to characterize the effect on the generation of OFC and the tuning of its offset frequency in a WGM resonator with opto-thermo-mechanical properties and pave the way for the future development of OFC in thermo-optomechanical environments.

Discrete ultra-slow optical solitons based on optomechanical effect.

We demonstrate that discrete solitons are possible in a micro-fabricated optomechanical structure, which consists of N identical cells. Analyses illustrate that these states originate from photon-phonon interaction or optomechanical effect. In principle, the self-localized entities are capable of exhibiting very slow velocities, depending on the photon hopping rate and phase difference among successive optomechanical cells.

Nonreciprocal light propagation in coupled microcavities system beyond weak-excitation approximation.

We propose a scheme for nonreciprocal light propagation in two coupled cavities system, in which a two-level quantum emitter is coupled to one of the optical microcavities. For the case of parity-time ([Formula: see text]) symmetric system (i.e.

Controlled switching of discrete solitons in periodically poled lithium niobate waveguide arrays.

We suggest an effective method for controlling nonlinear switching in one-dimensional waveguide arrays formed by the periodically poled lithium niobate. We demonstrate that the ability of switching for discrete solitons is relative to the coupling coefficient that is determined by the applied external electrical field on periodically poled lithium niobate waveguide arrays. Besides the external electrical field, the switching of the discrete solitons is also determined by the excited beams tilted angle.
