Abstract

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.

Acoustic field induced nonlinear magneto-optical rotation in a diamond mechanical resonator

Mohsen Ghaderi Goran Abad, Fatemeh Ashrafizadeh Khalifani, Mohammad Mahmoudi

We study the nonlinear magneto-optical rotation (MOR) of a linearly polarized microwave probe field passing through many nitrogen-vacancy (NV) centers embedded in a high-Q single-crystal diamond mechanical resonator. On the basis of the strain-mediated coupling mechanism, we establish a three-level closed-loop system in the ground states of the NV center in the presence of a static magnetic field. It is shown that by applying an acoustic field, the birefringence is induced in the system through the cross-Kerr effect, so that the probe field is transmitted with a high intensity and rotated polarization plane by 90 degrees. In addition, we demonstrate that the acoustic field has a major role in enhancing the MOR angle to 90 degrees. Moreover, it is shown that the MOR angle of the polarization plane after passing through the presented system is sensitive to the relative phase of the applied fields. The physical mechanism of the MOR enhancement is explained using the analytical expressions which are in good agreement with the numerical results. The presented scheme can be used as a polarization converter for efficient switching TE/TM modes in optical communication, the depolarization backscattering lidar, polarization spectroscopy and precision measurements.

Magneto-optical rotation in a GaAs quantum well waveguide

Ali Mortezapour, Mohsen Ghaderi Goran Abad, Mohammad Mahmoudi

The interaction of two orthogonally polarized beams and a four-level GaAs quantum well (QW) waveguide is investigated. It is shown that, by applying a static magnetic field normal to the propagation direction of the driving beams, the birefringence can be induced in the QW waveguide. Moreover, it is demonstrated that the dephasing rate between two ground states of the QW waveguide makes it a dichromatic medium and can also diminish the induced birefringence. Our results show how a large and complete magneto-optical rotation in the QW waveguide can be obtained via adjusting the intensity of the magnetic field and also the length of the QW waveguide.

Optical Nonreciprocity in Rotating Diamond with Nitrogen‐Vacancy Color Centers

Hongbo Huang, Jun‐Jie Lin, Yi‐Xuan Yao +3 more

Abstract A method to realize optical nonreciprocity in rotating nano‐diamond with nitrogen‐vacancy (NV) centers is theoretically proposed here. Because of the relative motion of the NV center with respect to the propagating fields, the frequencies of the fields are shifted due to the Doppler effect. When the control and probe fields are incident to the NV center from the same direction, the two‐photon resonance still holds as the Doppler shifts of the two fields are the same. Thus, due to the electromagnetically‐induced transparency, the probe light can pass through the NV center nearly without absorption. However, when the two fields propagate in opposite directions, the probe light cannot effectively pass through the NV center as a result of the breakdown of two‐photon resonance.

Polarization-selective excitation of nitrogen vacancy centers in diamond

Thiago P. Mayer Alegre, Charles Santori, Gilberto Medeiros‐Ribeiro +1 more

The nitrogen vacancy (NV) center in diamond is promising as an electron spin qubit due to its long-lived coherence and optical addressability. The ground state is a spin triplet with two levels $({m}_{s}=\ifmmode\pm\else\textpm\fi{}1)$ degenerate at zero magnetic field. Polarization-selective microwave excitation is an attractive method to address the spin transitions independently since this allows operation down to zero magnetic field. Using a resonator designed to produce circularly polarized microwaves, we have investigated the polarization selection rules of the NV center. We first apply this technique to NV ensembles in [100]- and [111]-oriented samples. Next, we demonstrate an imaging technique, based on optical polarization dependence, which allows rapid identification of the orientations of many single NV centers. Finally, we test the microwave polarization selection rules of individual NV centers of known orientation.

Magneto-optical rotation of surface plasmon polaritons

Habibur Rahman, Hazrat Ali, Iftikhar Ahmad +2 more

Abstract We investigate magneto-optical rotation (MOR) of surface plasmon polaritons (SPPs) at the interface of a metal and a four-level atomic system. The MOR of SPPs can be controlled and modified with the intensity and frequency of the applied fields. We show the birefringence enhancement of the weak probe fields propagating through the atomic medium in the presence of the static magnetic field. The external magnetic field has a vital role in the generation and control over the MOR of SPPs. The MOR completely stops when either the external magnetic field or the probe field or both are tuned to resonance. A pretty behavior of MOR of SPPs is observed for a specific set of control field frequency. The enhanced MOR of SPP has significant applications in atomic spectroscopy, optical communication, nano-photonics, optical switches, and precise measurement.

Orientation determination of nitrogen-vacancy center in diamond using a static magnetic field

Yangpeng Wang, Rujian Zhang, Yan Yang +3 more

Nitrogen-vacancy (NV) centers in a bulk diamond are often employed to realize measurement of multiple physical quantities, which depends on orientation information of NV axis. We report a fast and effective method to determine the orientation of NV axis with the aid of a static magnetic field. By measuring the optically detected magnetic resonance spectra, we can precisely extract the polar angle information between the NV axis and the known magnetic field. Combining with the polar angle information of different kinds of NV centers, we employ the Nelder–Mead algorithm to get the optimal solution of the orientation of NV axis. This method is simple and efficient, and is easily applied in NV-based quantum sensing.
