In this study, a ray tracing model based on the law of reflection in vector form was developed to obtain the design parameters of multipass cells (MPC) with dense spot patterns. Four MPCs with distinct patterns were obtained using an established mathematical model. An MPC with a four-concentr...
BEAM dynamicsDIFFERENTIAL equationsThe dynamics of light bullets propagating in nonlinear media with linear/nonlinear, gain/loss and coupling described by the (2+1)-dimensional vectorial cubic–quintic complex Ginzburg–Landau (CGL) equations is considered. The evolution and the stability of the vector...
12c. By using rationally photoaligned CLCs, detections including vector beam and hybrid OAM modes were all successfully realized, which greatly expands the role of LCs in optical communications. Fig. 12: LCs for light field modulation devices. a Transmissive vortex beams generated by diffraction fork...
Recently it has been shown that one can convert a vector beam in frequency while retaining the polarisation structure, but changing wavelength207,208,209, for faithful vectorial wavelength control. A recent development is the use of structured matter for non-linear control of structured light. ...
If the two components of the electric field along the x and y axes have equal magnitude but differ in phase by 90°, the tip of the electric field vector rotates on a circle and the light is circularly polarized. Elliptical polarization corresponds to the case where the two components of ...
2d)21. Furthermore, metasurface-integrated VCSELs have been used to construct various wavefronts, including those of Bessel beam generation21, vectorial holography reconstruction81, and beam steering21,82. Because both the VCSEL and metasurfaces are compatible with the same CMOS process, they may...
where i is the unit vector in the direction of polarization, ω is the angular frequency (2πν), and cm is the velocity of light in the medium, with the scalar amplitude being Ao. This LPL can be considered as composed of either two mutually orthogonal linearly polarized components at ±...
LIBSVMandLIBLINEAR: both packages provide Support Vector Regression (SVR) models in addition to classifiers. ForLIBSVM, setting the hyperparametersvm_typeallows for the training of epsilon-SVR (svm_type = 3) and nu-SVR (svm_type = 4).LIBLINEARallows for the training oflinearSVR by setting...

For example, a single ultrathin metasurface, composed of eight groups of rectangular nanoparticle arrays with various azimuth angles, was used to generate arbitrary vector beams [47]. An assembly of circularly polarized (CP) and linearly polarized (LP) states can be simultaneously generated by a ...
