“…Implementing room-temperature slow light is of fundamental importance in physics and also a challenging scientific subject, which may greatly promote the practical applications of slow light in information storage and optical communication [42]- [45]. In analogy to the previous slow-light investigations in optomechanical system [37]- [40], in the region of the narrow transparency window, the rapid phase dispersion can cause the group delay. Similarly, the rapid phase dispersion, that is, (ω) = arg[S 21 (ω)] = 1 2i ln( S 21 (ω) S 21 * (ω) ), can also be achieved in our scheme induced by magnon polaritons.…”

Realizing room-temperature slow light is of fundamental importance in physics and may promote the practical applications of slow light in information storage and optical communication. Here, we propose a feasible way to realize room-temperature slow light based on magnon-polaritons in a coupled cavity magnon-photon system, in which the cavity microwave photons strongly coupling with the magnons in a small-scale magnetic insulator yttrium-iron-garnet (YIG, Y 3 Fe 5 O 12 ). We find that the generation of slow light does not require the harsh conditions of ultra-low temperature, and the magnitude of the group delay can be regulated by adjusting the external magnetic field. Furthermore, the transformation between the fast and slow light can be achieved by controlling the magnon-photon coupling strength. Based on the current experimental condition, we believe that the proposed scheme of room-temperature slow light will be highly accessible in experiments. The potential applications range from enhancing magnon-photon interaction to designing an optical communication network.INDEX TERMS YIG, magnon-polaritons, slow light, room temperature.The associate editor coordinating the review of this manuscript and approving it for publication was Wenjie Feng.

“…In this section, we will discuss the enhancement of superluminal light in hybrid system by changing different system parameters. To explain the mathematical results we choose experimentally realizable parameters as follows: the wavelength λ = 794 nm, total length of cavity l = (1–25) × 10 −3 m, mass of moving mirror m = 5 − 145 ng, frequency of the oscillating mirror ω m = 2 π × 10 MHz, a strong pump field ε l = 0.5 other following parameters are scaled by ω m = 1 MHz [38, 39], cavity decay rate κ = 0.2, the decay‐rate of mechanical oscillator γ = 1.4 × 10 −4 , frequency of driving field

We investigate the superluminal effect of transmitted probe field in three‐level quantum dot molecules (QDMs) assisted optomechanical system which consist of mechanical resonator. We show that the superluminal behavior of transmitted probe field can be controlled by changing the tunneling strength and number of QDMs inside the cavity. Furthermore, it is shown that in the absence of tunneling strength, the transmitted probe field shows the fast light effect and by increasing the number of QDMs, the enhancement in superluminal behavior is decreased and converts into slow light. While, in the presence of the tunneling strength, with the increase of the number of QDMs the superluminal behavior of transmitted field is obtained at smaller detuning frequency. The influence of tunneling strength and number of QDMs on superluminal part of the transmitted probe field is quite useful in optical memory, optical buffers, and quantum information processing.

A theoretical model is presented to study the hybrid optomechanical system comprising an ensemble of N number of quantum dots (QDs). Utilizing the Holstein-Primakoff (H-P) transformation formalism, the calculations become easily scalable. The bistability in this hybrid optomechanical system is studied in the presence of third order nonlinear 𝝌 (3) medium using the H-P transformation method and to verify the results, numerical method has also been utilized. It is also demonstrated that the system's parameters may be tuned to alter the bistability phenomenon and absorption spectrum's response, which exhibits both positive and negative absorption (emission). This alternative approach (H-P transform) is demonstrated to solve analytically the system containing multiple QDs in an elegant manner.
