“…[13][14][15]. For instance, a distinct phenomenon known as an electromagnetically induced grating (EIG) is produced when the control field is switched out for a standing wave (SW) [8,[16][17][18][19][20][21][22]. The amplitude and dispersion of the probe field become spatially periodic as a result of SW patterning of the coupling light.…”

In this letter, we have put out a fresh idea for managing the diffraction sample of optical vortex light that was transmitted from a four-level quantum dot molecule. We describe the creation of a new weak laser field via inter-dot tunneling, which causes the diffraction grating to be dependent on the orbital angular momentum (OAM) of the optical vortex light. We found that the relative phase between the implemented lights and the OAM number of the vortex light affect the intensity distribution of the asymmetric grating. Additionally, we discovered that the maximum amount of probe energy could be dispersed in higher orders of diffracted angles that were negative and positive by modifying the inter-dot tunneling and OAM number.

“…It is worth pointing out that the phase-dependent EIT may have some remarkable outcomes different from the conventional EIT. It provides the opportunity to control the optical properties only by the laser phases, without changing neither frequencies nor input intensities [37]. This would offer an extra degree of freedom in controlling the medium response in a more sophisticated manner than in the conventional EIT.…”

We analyze the electromagnetically induced grating in a four-level inverted-Y double quantum well system. Based on the electromagnetically induced transparency, the Fraunhofer diffraction of a weak probe laser field is theoretically investigated. It is shown that the diffraction patterns are sensitive to both the absorptive and dispersive properties of the system. The effect of coupling and pumping fields intensity, frequency detuning, the relative phase of fields and the sample interaction length on diffraction pattern is then discussed. Our scheme may find potential applications in designing the semiconductor quantum well-based photonic devices, such as all-optical switches at low light levels.
