“…These special light beams have helical (twisted) wavefronts that spiral along the beam's direction like a corkscrew [21]. These kinds of optical vortex beams have a characteristic phase factor and behave interestingly in atomic interactions [22][23][24][25][26]. Light-induced torque [27], atom vortex beams [28], OAM-based four-wave mixing [29], entanglement of OAM states in photon pairs [19], and spatially structured optical phenomena [30][31][32][33][34][35][36] are a few of the remarkable effects.…”

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.

“…Chen studied [8] the Fraunhofer diffraction pattern of the output field in a nonlinear optomechanical cavity with a degenerate optical parametric amplifier and a higher order excited atomic ensemble. Very recently, Asadpour et al [37] proposed a new model for the spatial controlling of the Fraunhofer diffraction pattern via composite vortex light. It has been found that by controlling the orbital angular momentum of composite vortex light, the spatial properties of the different orders of the grating can be manipulated.…”

The experimental realization of two-dimensional (2D) electromagnetically induced grating is explored by monitoring the Fraunhofer diffraction pattern in a microwave-driven four-level Y-type atomic medium under the action of two orthogonal standing-wave (SW) fields. Due to the position-dependent atom–field interaction, the information about the high diffraction order of the probe light can be obtained via the Fraunhofer diffraction pattern of the probe light. It is found that the diffraction behavior is significantly improved due to the joint quantum interference induced by the SW and microwave-driven cycling fields. Most importantly, the amplitude and phase diagram of the transmission function of the probe light can be modulated at a particular position and the probe energy may transfer to the high orders of the diffraction by properly adjusting the system parameters. The proposed scheme may provide a promising way to achieve highly sensitive diffraction patterns with applications in quantum information processing.
