Abstract

Abstract This work introduces a novel model to manipulate electromagnetically induced gratings within systems based on nitrogen-vacancy (NV) centers. The system is driven by coherent laser sources comprising a weak probe and standing-wave-patterned coupling fields aligned along the x and y axes, which induce spatial modulation of the refractive index, resulting in the emergence of Fraunhofer diffraction. Our investigation delves into the modulation and diffraction behaviors of transmitted light within the NV system, with a focus on examining the influence of various parameters, particularly magnetic fields. Our findings highlight how magnetic fields strongly influence the transmitted light, altering its intensity and phase characteristics, as well as the resulting diffraction structure. Specifically, we observe a notable redistribution of energy between zero and higher diffraction orders as the magnetic field deviates from zero, showcasing the versatility of magnetic field as a tool for manipulation of diffraction grating powers, thereby offering flexibility in optical output engineering. These findings open new avenues for precise tuning and performance enhancement of resonant optical systems, with potential applications spanning photonic technologies and optical signal manipulation.

Electromagnetically induced grating in azimuthal dependent three-level quantum dot system

Abstract The Fraunhofer diffraction pattern in a three-level quantum dot nanostructure is examined. A probe light, a two-dimensional standing wave field, and a weak signal light are the three optical laser fields that the graphene quantum dot interacts with them. The Fraunhofer diffraction pattern of the probe transmitted light has been addressed under two different coupling situations, including when the weak signal light into an optical vortex beam and a plane wave. The Fraunhofer diffraction pattern becomes symmetric for plane wave coupling light, and the diffracted light can be adjusted by the relative phase between applied lights. However, using the orbital angular momentum of light, it is possible to obtain an asymmetric diffraction pattern for optical light. It has been discovered that in both instances, phase modulation of the probe light’s transmission function allows the probe energy to move from zero order to higher orders.

Magneto-optical rotation in the diamond nitrogen-vacancy center

Ali Mortezapour, Mohsen Ghaderi Goran Abad, Mahdi Ahmadi Borji

Abstract The interaction of two orthogonally polarized beams and a diamond nitrogen vacancy (NV) center sample is investigated. It is shown that applying a static magnetic field parallel to the propagation direction of the probe beam makes the diamond NV center sample a birefringent medium. Electromagnetically induced transparency (EIT) is attained under the assumption of specific parameters. Moreover, it is demonstrated that the magneto-optical rotation (MOR) can be manipulated by the control beam. Our results show that how a large and complete MOR can be obtained by adjusting the intensity of the magnetic field and the length of the diamond NV center sample.

Controlling 2D-fraunhofer diffraction in nonlinear optomechanical systems with atomic ensembles

Ning Fu, Pengju Kuang, Lei Ni +2 more

Abstract In this letter, we propose a novel nonlinear optomechanical system for generating a two-dimensional (2D) optical grating. The system comprises a Fabry–Pérot cavity with a fixed mirror, movable end mirror, degenerate optical parametric amplifier (OPA), and ensemble of identical two-level atoms. By applying a 2D asymmetric standing wave as the driving field, the probe light can be diffracted in the x - and y -directions with different intensities, leading to an asymmetric optomechanically induced grating. The amplitude and phase modulations of the output probe light and the resulting Fraunhofer diffraction patterns were investigated. The results show that the atomic ensemble plays a crucial role in controlling the efficiency and asymmetry of 2D gratings. We demonstrate that by tuning the nonlinear gain of the OPA and higher-order excitations of the atoms, the transparency of the medium can be enhanced, leading to greater transmission of probe energy and transfer to higher diffraction orders. The proposed system offers a novel approach for generating asymmetric 2D optical gratings in optomechanical devices with potential applications in quantum information science.

Azimuthal modulation of electromagnetically induced grating using structured light

Seyyed Hossein Asadpour, Teodora Kirova, Jing Qian +3 more

We propose a theoretical scheme for creating a two-dimensional Electromagnetically Induced Grating in a three-level [Formula: see text]-type atomic system interacting with a weak probe field and two simultaneous position-dependent coupling fields-a two dimensional standing wave and an optical vortex beam. Upon derivation of the Maxwell wave equation, describing the dynamic response of the probe light in the atomic medium, we perform numerical calculations of the amplitude, phase modulations and Fraunhofer diffraction pattern of the probe field under different system parameters. We show that due to the azimuthal modulation of the Laguerre-Gaussian field, a two-dimensional asymmetric grating is observed, giving an increase of the zeroth and high orders of diffraction, thus transferring the probe energy to the high orders of direction. The asymmetry is especially seen in the case of combining a resonant probe with an off-resonant standing wave coupling and optical vortex fields. Unlike in previously reported asymmetric diffraction gratings for PT symmetric structures, the parity time symmetric structure is not necessary for the asymmetric diffraction grating presented here. The asymmetry is due to the constructive and destructive interference between the amplitude and phase modulations of the grating system, resulting in complete blocking of the diffracted photons at negative or positive angles, due to the coupling of the vortex beam. A detailed analysis of the probe field energy transfer to different orders of diffraction in the case of off-resonant standing wave coupling field proves the possibility of direct control over the performance of the grating.

Phase controlling of electromagnetically induced grating

Zuge Tang, Behrad Zeinali, Sarkew Salah Abdulkareem

Abstract In this paper, we investigated electromagnetically induced grating in a three-level atomic system via relative phase between applied lights. The three-level atomic system interacts with a weak probe light, a signal light and a strong standing wave coupling light in two-dimensional directions. We realized that Fraunhofer diffraction pattern can be obtained by tuning the intensity and detuning’s of the coupling light. We also use of optical vortex light instead of optical plane wave and found that the asymmetric diffraction pattern can be obtained via orbital angular momentum (OAM), respectively. We also studied the different orders of the diffraction pattern versus relative phase of applied lights for different number of OAM.

Magnetically controlled optical modulator based on coherent perfect absorption in NV centers

Ming-feng Jiao, Chang-Shui Yu

We design an optical modulator based on an optical resonant cavity that coherently couples to an ensemble of nitrogen-vacancy (NV) centers, controlled by an external magnetic field. We reveal the coherent perfect absorption (CPA) of photons in the system and demonstrate how to suppress, block, and amplify light transmission by manipulating the amplitude, direction, and detuning of the external magnetic field, as well as the phase difference between the input light fields. This design leverages the friendly controllability of NV centers by an external magnetic field, suggesting the potential to develop advanced photonic devices.
