Magneto-optical rotation in the diamond nitrogen-vacancy center

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.

“…Rotation of right and left CP probe beam has some interesting application in the field of spectroscopy, magnetometry, communication optics, sensors, atomic clocks, optical limitation, birefringence based optical filters, and quantum memory [6][7][8][9][10][11][12]. MOR was observed in different atomic media both, theoretically and experimentally [13][14][15][16][17][18][19][20].…”

Dynamics of induced optical torque via optical vortex light

“…This prominence is attributed to their enduring electronic spin decoherence time, a notable feature even at room temperature [30][31][32][33][34][35][36]. Recent years have witnessed a surge in research exploring the extensive properties and intriguing phenomena associated with NV centers, recognizing their potential pivotal roles in quantum information and computing [37][38][39][40][41][42][43][44][45]. Pioneering studies include the successful demonstration of coherent population trapping in a single NV center within a diamond under optical excitation, showcasing the feasibility of all-optical control over single spins in diamond [37].…”

“…Another captivating study involves the three-dimensional localization of a single NV center in nanodiamond using positiondependent standing-wave laser fields in an external magnetic field [43]. Mortezapour et al have also explored the phenomenon of magneto-optical rotation within diamond NV centers, contributing to an enhanced understanding of the potential applications and capabilities of these quantum entities [44].
