“…Such atomic grating can serve as a diffraction grating or a Bragg grating depending to the propagation direction of probing light with regard to the standing-wave. Many applications based on EIG have been proposed, such as optical bistability [17], optical switching and routing [18], beam splitting and fanning [19], stationary light pulse [20], coherently induced photonic bandgap [21] and surface solitons [22]. EIG was first put forth in a three-level system by Ling and colleagues [16], after that many groups [12][13][14][23][24][25] observed it.…”

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.
