“…The above approaches to generate vector optical beams with longitudinally varying polarization in free space all rely on digital phase mask [51], enabled by SLM, and require a particular SoP at the input plane. Recently, a form-birefringent was demonstrated by The above approaches to generate vector optical beams with longitudinally varying polarization in free space all rely on digital phase mask [51], enabled by SLM, and require a particular SoP at the input plane. Recently, a form-birefringent was demonstrated by Capasso et al to impart the arbitrary polarization along the propagation direction without a priori knowledge of the incident polarization [52].…”

The vector optical beam with longitudinally varying polarization during propagation in free space has attracted significant attention in recent years. Compared with traditional vector optical beams with inhomogeneous distribution of polarization in the transverse plane, manipulating the longitudinal distribution of polarization provides a new dimension for the expansion of the applications of vector optical beams in volume laser machining, longitudinal detection, and in vivo micromanipulation. Two theoretical strategies for achieving this unique optical beam are presented in the way of constructing the longitudinally varying phase difference and amplitude difference. Relevant generation methods are reviewed which can be divided into the modulation of complex amplitude in real space and the filtering of the spatial spectrum. In addition, current problems and prospects for vector optical beams with longitudinally varying polarization are discussed.

The strategy of parallel factor analysis, combined with the internal standard method, has been increasingly applied to the qualitative and quantitative analysis of three-dimensional fluorescence spectra of unknown mixed fluorophores. Nevertheless, the disparity in the number of fluorophores included in the internal standard sample set and the number included in test samples may impact the qualitative and quantitative outcomes of parallel factor analysis. In this work, we systematically established the framework of the parallel factor analysis with internal standard sample embedding (ISSE-PARAFAC) strategy. We applied this framework to six datasets representing two scenarios and conducted a detailed discussion on the effects of the disparity between the number of fluorophores in the internal standard sample set and the number in the test set on both qualitative and quantitative results. Additionally, we introduced an enhancement to PARAFAC by aggregating fluorophores with similar emission wavelengths, corresponding to the peaks of emission loadings (spectra) obtained from PARAFAC, as a single fluorophore. This aggregation aimed to mitigate the strong correlation between similar fluorophores. The results imply that the presence of irrelevant fluorophores in the internal standard sample set, whether increased or decreased, does not significantly affect the qualitative and quantitative analysis of target fluorophores in the test set. Moreover, we demonstrated that the improved parallel factor analysis with internal standard sample embedding not only fully decomposes the uncorrelated mixed fluorophores for qualitative analysis but also allows the established linear concentration model for fluorescent components to predict the corresponding fluorophore concentration of test samples, enabling quantitative analysis at the ppm level (µg/mL).

“…SAM is inherent in light beams with elliptical polarization states and depends on the field vector rotations that take place at every point of the beam crosssection. [9,10] The SAM degree of freedom of light plays a key role in optical communication systems. [11,12] For example, dual polarization in fiber optic eigenvalue communication has been reported recently in order to overcome the limitation of information transmission in conventional optical communication systems.…”

Optical vortices with tunable polarization states and topological charges are widely investigated in various physical systems and practical devices for high-capacity optical communication. However, this kind of structured light beams are usually generated using several polarization and spatial phase devices, which decreases the configurability of optical systems. Here, we have designed a kind of polarized optical multi-vortices generator based on Stokes-Mueller formalism and cross-phase modulation. In our scheme, multi-channel generation of polarized vortex beams can be realized through a single optical element and a single-input Gaussian beam. The polarization states and orbital angular momentum of the generated light beams are all-optically controllable. Furthermore, the proposed polarized optical multi-vortices generator has also been demonstrated experimentally through one-step holographic recording in an azobenzene liquid-crystalline film and the experimental results agrees with theoretical analysis.
