“…With the development of novel materials and structures, the GH and IF shifts can be enhanced and modulated effectively in various materials, such as graphene [6][7][8][9][10][11], weakly absorbing dielectric [12][13][14][15], photonic crystal [16][17][18], plasmonics [19,20] and nonoptical systems [21][22][23][24][25]. In addition, the GH and IF shifts have potential applications in optical sensors [26,27], image edge detection [28] and optical switches [29,30].…”

We theoretically derive the expression for the Goos-Hänchen(GH) and Imbert-Fedorov(IF) shifts of the Airy beam in Dirac metamaterial. In this work, the large GH and IF shifts can be found when the Airy beam is reflected near the Dirac and Brewster angles. Compared to the Gaussian beam, the GH shifts of the Airy beam are more obvious in the vicinity of the Brewster angle. Interestingly, it is found that the ability to produce an Airy vortex beam at the Dirac point. In addition, the magnitude and the direction of the GH shifts can be controlled by the rotation angles of the Airy beam. We take advantage of this property to design a reflective optical switch based on the rotation angle-controlled GH shifts of the Dirac metamaterial. Our solutions provide the possibility to implement light-tuned optical switches. Moreover, our model can also be used to describe the GH and IF shifts generated by novel beams in other similar photonic systems

“…Modern photonics has the capacity to perform a multitude of operations through the utilization of nonlinear optics, such electromagnetically induced transparency [1], optical solitons [2], four-wave mixing [3] and others [4][5][6][7][8]. Typically, intense field intensities are required to alter the optical properties of materials to engender nonlinear effects [9][10][11]. Nevertheless, efficacious nonlinear devices with low light intensity can be generated by utilizing the potent localization of electromagnetic field in the form of surface plasmon polaritons [4,7,[12][13][14][15].…”

In this letter, a comprehensive investigation has been conducted on the optical bistability (OB) and optical multistability (OM) phenomena manifested by transmitted light in a ring cavity consisting of a hybrid system of metal nanoparticle (MNP) and semiconductor quantum dot (SQD). Our study has been primarily devoted to examining the influence of the distance between SQD and MNP, as well as the susceptibilities of the SQD, the MNP, and the hybrid nanostructure as a whole, on the OB and OM traits of the transmitted light. Our discoveries demonstrate that a transition from OB to OM, or vice versa, can be accomplished for a definite distance between MNP and QD. It is our contention that our proposed model may have potential applications in the domain of quantum information processes based on SQD-MNP hybrid systems.

“…Electromagnetically induced transparency (EIT) is a fascinating quantum optics phenomenon that occurs when a strong coupling field interferes with a weak probe field, causing its absorption to vanish [1]. This effect has found applications in numerous domains, including optical bistability [2,3], enhanced Kerr nonlinearity [4], and optical solitons [5,6], four-wave mixing (FWM) [7,8] and so on [9][10][11][12][13].…”

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.
