Orbital angular momentum-dependent transmission in a hybrid optomechanical cavity with composite vortex light

Abstract

Abstract The theoretical investigation into spatially coherent control over electromagnetically induced transparency is carried out within a hybrid cavity system comprising a three-level atomic configuration, a mechanical resonator, and an optical cavity. The interaction involves driving a composite vortex light (CVL) with a three-level medium. Our findings reveal that the input-output cavity field can be systematically adjusted, resulting in changes to the transmission spectrum of the weak probe light. The transmission spectrum of the output light can be spatially controlled by manipulating the orbital angular momentum of the CVL and through parametric modulation of the system. Our simulations present a flexible approach for managing light-matter interactions in a hybrid optomechanical system.

Spatially control of dispersion in a three-level assisted optomechanical system

Bin Xiao, Yan Huang

Abstract In this letter, we propose a new model based on an optomechanical system to control the spatial properties of the dispersion spectrum of a weak cavity field. The optomechanical cavity consists of a three-level atomic system with ladder-type configuration. The atomic system interacts with the composite vortex light and a weak cavity field. The composite vortex light carries an orbital angular momentum (OAM), which can be used to adjust the spatial properties of the medium. We found that by controlling the OAM number of the composite vortex light, the spatial pattern of the dispersion spectrum can be controlled in different regions of space. By adjusting the dispersive control of the medium, the refraction and group indices can be optimized for application in quantum information processing.

Optomechanically induced transparency in a Laguerre-Gaussian vortex cavity system assisted by a four-wave-mixing atomic ensemble

Yue-Tong Hao, Yi-Mou Liu

We investigate the steady-state optical response of a Laguerre-Gaussian vortex cavity system integrated with cold atoms featuring a double-$\mathrm{\ensuremath{\Lambda}}$ energy level structure. Within this hybrid system, the atoms are driven by a cavity mode and three coherent vortex beams, each carrying independent orbital angular momentum. We first check the steady-state output spectrum of the hybrid system in the passive (active) case [without (with) external cavity driving]. Our findings reveal that the optomechanically induced transparency spectrum is modulated by the orbital angular momentum difference $(\mathrm{\ensuremath{\Delta}}\ensuremath{\ell}\ensuremath{\hbar})$ from the atomic component throughout the four-wave-mixing process. The resulting loop phase (${\ensuremath{\ell}}_{\mathrm{\ensuremath{\Theta}}}\ensuremath{\theta}$) can achieve a switching effect on the absorption and gain behavior of the hybrid system for the probe beam. Additionally, the group delay, indicative of fast or slow light phenomena, is also tuned by $\mathrm{\ensuremath{\Delta}}\ensuremath{\ell}$. We further display how the atomic orbital angular momentum modulates the periodicity of the output spot pattern in the hybrid system. This research provides valuable insights into the modulation of optical responses in Laguerre-Gaussian vortex cavity systems.

Angular momentum conversion in the influence of vortex light on electromagnetically induced transparency

Tang Jiangmin, ZHANG Jingtao

In the burgeoning field of light-matter interactions, angular momentum has emerged as a pivotal factor, driving innovative research directions. This study delves into the interaction dynamics between vortex lights and an electromagnetically induced transparency (EIT) medium, with a primary focus on elucidating the underlying mechanism of angular momentum transfer. Through comprehensive theoretical analysis and numerical simulations, it is demonstrated that when the probe field carries orbital angular momentum (OAM), the dispersion and absorption characteristics of the EIT medium undergo periodic modulation. This modulation is intricately determined by the azimuthal phase and topological charge of the beam. Notably, the OAM in the driving field exerts no such influence on the medium's properties. Leveraging vortex phase plates (VPPs) or spatial light modulators (SLMs) to manipulate the tunable OAM enables dynamic control over the EIT effect. This breakthrough not only deepens our understanding of light-matter interactions at the quantum level but also unlocks new avenues for high-dimensional quantum information processing and advanced optical communication technologies.

Optical grating in a three-level assisted optomechanical system

Anjan Kumar, Sanaa Fathy Mahmud, Hasan Khalid Dabis +8 more

Abstract The phenomena of electromagnetically induced gratings are theoretically discussed in a hybrid cavity system consisting of a three-level atomic scheme, a mechanical resonator, and an optical cavity. A driving light with a two-dimensional standing wave pattern interacts with a three-level medium. We discovered that the input–output cavity field can be altered on a regular basis, which leads to modification of the weak probe light’s Fraunhofer diffraction pattern at the resonance frequency. Thus, by parametric modulation of the system such as the driving light’s intensity and cavity parameters, we may regulate the energy of the probe field in different orders of the grating. Our simulations may offer a versatile method for regulating atomic gratings in hybrid optomechanical systems.

Optomechanically induced transparency in Four-wave mixing atomic ensemble assisted Laguerre-Gaussian vortex cavity system

Yue Hao, Yi-Mou Liu

We investigate the steady-state optical response of a Laguerre-Gaussian vortex cavity system integrated with cold atoms featuring a double-$Λ$ energy level structure. Within this hybrid system, the atoms are driven by cavity mode and three coherent vortex beams, each carrying independent orbital angular momentum (OAM). We first check the steady-state output spectrum of the hybrid system in the passive/active case (without/with external cavity driving). Our findings reveal that the optomechanically induced transparency (OMIT) spectrum is modulated by the OAM difference $(Δ\ell\hbar)$ from the atomic component throughout the four-wave mixing (FWM) process. The resulting loop phase ($Δ\ellθ$) can achieve a switching effect on the absorption and gain behavior of the hybrid system for the probe beam. Additionally, the group delay, indicative of fast/slow light phenomena, is also tuned by $Δ\ell$. We further display how the atomic OAM modulates the periodicity of the output spot pattern in the hybrid system. This research provides valuable insights into the modulation of optical responses in Laguerre-Gaussian vortex cavity systems.

Spatially structured optical effects via composite vortex light in a dielectric medium

Ahmed Ahmed Ibrahim, Shaymaa Abed Hussein, Sanaa Fathy Mahmud +9 more

Abstract In this letter, we have proposed a model for spatially structured transmitted and reflected lights from dielectric medium consists of four-level coherent system. An elliptically polarized probe field and a composite vortex light in the presence of external magnetic field are interacted by this medium. We have shown that by controlling the external magnetic field, ellipticity of the probe light and orbital angular momentum (OAM) of the composite vortex light, the transmitted and reflected lights can be controlled. We have also found that due to the spatial pattern of the composite vortex light, the spatially pattern light amplification can be obtained by adjusting the spatial control of the transmitted and reflected lights. In other word, by tuning the OAM number of the composite vortex light and external magnetic field, the spatial controlling of the transmitted and reflected lights are possible and this leads to controlling the high-gain spatially pattern regions.
