“…primarily based on quantum interference phenomena and atomic coherence [5][6][7]. The foundations of quantum coherence and interference extend to atom-field interactions [8][9][10][11], measurement theory [12], enormous Kerr nonlinearities [13], and many other areas of atomic physics and quantum optics [14][15][16][17]. For quantum interference-based 1D atom grating, several different techniques have been presented [18][19][20][21].…”

“…It was realized that the intensity of the first order of the diffraction depends on the probe detuning and amplitude of the SW fields. Recently, several models have been proposed for controlling the Fraunhofer diffraction pattern in different quantum systems [8,10,11,[31][32][33][34][35][36]. 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.…”

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.

“…Semiconductors have been shown to exhibit EIT through intersubband transitions [36], electron spin coherence (ESC) in a quantum well waveguide [37][38][39][40][41][42], and nonradiative quantum coherences [39]. Such quantum coherence can be harnessed to observe various quantum phenomena in semiconductors, such as gain without inversion, coherent control of absorption and dispersion, and FWM, all made possible by intersubband optical transitions [43][44][45][46][47][48][49][50][51].…”

In this paper, we delve into the intricate interplay between optical fields with varying relative phases in a closed-loop configuration semiconductor quantum well waveguide with four distinct energy levels, and how it impacts the Fraunhofer diffraction patterns obtained via four-wave mixing. By harnessing a strong control field, a standing wave driving field, and two weak probe and signal fields, we drive the waveguide to generate these patterns with maximum efficiency. To achieve this, we consider three distinct light-matter interaction scenarios, where the system is first set up in either a lower electromagnetically induced transparency or a coherent population trapping state, followed by a final state that enables electron spin coherence (ESC) induction. Our results reveal that the efficiency of Fraunhofer diffraction in the quantum well waveguide can be enhanced significantly under specific parameter regimes via the spin coherence effect. Further investigation of the light-matter interaction in the ESC zone, where only one of the control fields is a standing wave field, demonstrates that spin coherence facilitates more efficient transfer of energy from the probe light to the third and fourth orders, highlighting its crucial role in shaping the diffraction patterns.

In this paper, we study the Fraunhofer diffraction pattern in a four-level quantum dot nanostructure. The quantum dot interacts with two weak probe and signal laser fields and two strong coupling lights where one of them is a two-dimensional standing wave field. We study the Fraunhofer diffraction pattern of the transmitted probe light when the coherent driving light becomes plan wave or Laguerre Gaussian (LG) vortex light. We found that by controlling the relative phase of the applied lights and orbital angular momentum (OAM) of LG light, the Fraunhofer diffraction pattern can be controlled and the probe energy transfer from zero order to the higher orders, respectively. Moreover, we realized that by controlling the OAM number of the vortex light the asymmetric diffraction pattern is possible.
