“…The idea exploited the simultaneous fulfillment of two phase matching conditions that reinforce one another. Using a long medium approximation, radial and angular mode conversion by FWM in a heated Rb vapour was demonstrated, making evident the role of the Gouy phase-matching in this regime 170 . Beyond just spatial DoFs, the spatial and temporal DoFs are not independent in this process 171 , where frequency control enables selection of various spatial modes as outputs.…”

The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven by the tremendous developments in the toolkit for the creation, control and detection of what is now called structured light. Because the complexity of these optical fields is generally understood in terms of interference, the tools have historically been linear optical elements that create the desired superpositions. For this reason, despite the long and impressive history of nonlinear optics, only recently has the spatial structure of light in nonlinear processes come to the fore. In this review we provide a concise theoretical framework for understanding nonlinear optics in the context of structured light, offering an overview and perspective on the progress made, and the challenges that remain.

“…In addition to using a SLM to adjust the angle between two pump beams, Swaim et al also proposed a new FWM geometry with a structured pump, which is generated by using near-field diffraction through a slit [141] . As shown in Fig.…”

“…The spatial multiplexing based on cascaded FWM in the previous subsection shares one pump beam for generating two independent FWM processes. At the same time, Wang et al [137] , Zhang et al [138] , Liu et al [139,140] , Swaim et al [141] , and Knutson et al [142] also demonstrated the spatially multiplexed FWM process in an atomic vapor cell by utilizing a spatially structured pump. This subsection focuses on generating spatially separated six, ten, and fourteen quantum correlated beams, as well as four bright beams in this way.…”

.The four-wave mixing process in atomic ensembles has many important applications in quantum information. We review recent progress on the generation of optical quantum states from the four-wave mixing process in hot atomic ensembles, including the production of two-beam, multi-beam, and multiplexed quantum correlated or entangled states. We also review the applications of these optical quantum states in implementing quantum information protocols, constructing SU(1,1) quantum interferometers, and realizing quantum plasmonic sensing. These applications indicate that the four-wave mixing process in hot atomic ensembles is a promising platform for quantum information processing, especially for implementing all-optical quantum information protocols, constructing SU(1,1) interferometers, and realizing quantum sensing.

Multipartite quantum correlation plays a vital role in potential applications of quantum technologies. In this paper, using energy‐level cascaded four‐wave mixing (EC‐FWM) process, a scheme to produce quantum correlated three‐mode light beams within a single device of hot atomic medium of rubidium is proposed. Two‐ and three‐mode amplitude, phase quadrature squeezing and intensity difference squeezing using energy‐level simultaneous cascaded FWM (ESC‐FWM) method and energy‐level ordinal cascaded FWM (EOC‐FWM) method, respectively, is theoretically reported. Via investigating their covariance matrix properties, the comparison has been made between the two methods, which shows the ESC‐FWM method has a more stable mode structure than EOC‐FWM method. Moreover, versatile gain dependent squeezing via EC‐FWM is studied and analytical expressions are given. These results show a simplified and efficient experimental scheme producing multipartite quantum correlation among multiple spatially separated beams.
