“…Considering Equations ( 6), (9), and ( 14), we observe that the local degree of polarization of the synthesized partially coherent beam is equal to the global degree of polarization of the encoded FP polarization state. Interestingly, throughout the transformation from incoherent light to a partially coherent beam, both the global degree of polarization and the vector quality factor of the beam remain constant.…”

“…Optical vector beams with spatially nonuniform polarization states have garnered significant attention over the past two decades due to their extraordinary properties, finding diverse applications such as optical imaging, optical trapping, and optical communications [1][2][3][4][5][6][7][8][9][10]. Among various vector beams, the full Poincaré (FP) beam stands out for its uniqueness, which presents all possible polarization states simultaneously on the Poincaré sphere within its beam cross-section [11].…”

The full Poincaré (FP) beam, encompassing all possible polarization states in its beam cross-section, has demonstrated advantages in various applications. However, conventional FP beams are typically considered as spatially fully coherent, rendering them sensitive to disturbances in the propagation path and susceptible to speckle effects. In this work, we propose an alternative approach to synthesize the optical beam with a FP polarization state through the spatial coherence engineering of a partially coherent beam. In this process, the FP polarization state is initially encoded into the spatial coherence structure of the beam source. We demonstrate that during the encoding process, the vector nature of the beam transitions from the FP polarization state to the spatial coherence structure of the source. However, during the propagation of the partially coherent beam, the vectorness reverts to the polarization state, resulting in the re-emergence of the encoded FP polarization in the output plane. We illustrate that the synthesized FP polarization state, achieved through spatial coherence engineering, is highly robust against obstructions in the propagation path. Furthermore, we examine the effect of the spatial coherence area of the beam on the quality of the recovered FP polarization state. The findings of this work can have valuable applications in optical trapping and optical imaging in complex environments.

“…2,3 Of special interest are vector beams composed of light modes carrying orbital angular momentum (OAM) imprinted onto right and left circular polarised light components, which carry spin angular momentum (SAM), leading to vector vortex beams in which extrinsic and intrinsic angular momenta are coupled, [4][5][6] with interesting effects for strong focusing, 7 non-classical correlations, and vectorial light matter interactions. [8][9][10][11][12][13][14][15][16][17][18][19] Atoms provide a valuable interface for vector light because dipole interaction depends, by its very nature, on the alignment between the oscillation direction of the light and the dipole moment of the atom. Rb-87 has a lambda configuration on the F = 1 → F ′ = 0 transition of the D2 Line (780 nm).…”

In this paper we expand and generalise the theoretical work underlying the results presented by F. Castellucci et al. in the paper at Ref. 1, offering an exploration into different regimes of vector light and light matter interaction as well as the inner atomic processes, such as the populations of newly derived partially dressed states which highlight the connection between polarisation and magnetic coupling, and the orbitals they correspond to. This deeper knowledge will not only increase our understanding of how light-atom interaction is impacted by the presence of magnetic fields, and is a step in improving this new method of magnetometry.

“…[44][45][46] Remarkably, exploring the vectorial nonlinear interactions driven directly by SOC light from 2D structure to 3D polarization Möbius strip, [47][48][49][50][51][52] has recently introduced a range of fascinating optical phenomena and functionalities, such as superresolution interferometric metrology, [53] designable light filaments [54,55] as well as controllable distortion of polarization and spatial profile. [56,57] Vectorial nonlinear optics offers a new platform for nonlinear control of SOC light as well as control of nonlinear processes by SOC light. However, the SOC-mediated nonlinear optical processes especially in an atomic medium is still in its infancy.…”

Recently, the vectorial nonlinear optical processes driven by spin‐orbit coupling (SOC) light have come to the fore, leading to striking optical phenomena and important applications both in classical and quantum optics. However, research on the SOC‐mediated light‐atom interactions is still in its infancy. Here, the generation and manipulation of SOC mode through a vectorial four‐wave mixing (FWM) process in 85Rb vapor is demonstrated. Under the excitation of two SOC pump beams, multiple FWM paths can be simultaneously established due to the rich atomic Zeeman sublevels coupling with different circularly polarized components of SOC fields. A higher‐order cylindrical or more general SOC FWM signal is observed in the vectorial FWM process, which obeys angular momentum conservation and Gouy phase matching. In particular, quantum interference between different FWM paths plays a crucial role in manipulating the SOC mode of the generated FWM signal, revealing that the conversion of SOC mode is intrinsically quantum. This work provides a pathway toward deeper insight into the vectorial nonlinear optical processes and may advance technology for shaping spatially structured light, which is essential in applications such as nonlinear polarization imaging and the optical communication realm.
