DOI: 10.1016/j.optcom.2018.12.040
Abstract: Abstract We demonstrate the generation of non-paraxial accelerating beams by using an objective with an external spherical aberration compensation. A correction phase is applied at an illuminating plane before the objective, and such an aberration-corrected… read more here.

DOI: 10.1088/0256-307x/40/5/053701
Abstract: Tractor beams, being able to produce optical pulling forces (OPFs) on particles, are attracted increasing attention. In this paper, non-paraxial Bessel tractor beams were generated by using polarization-insensitive metasurfaces. The OPFs were found exerted on… read more here.

DOI: 10.1088/1367-2630/ab5da8
Abstract: We show that quantum fluids enable experimental analogs of relativistic orbital precession in the presence of non-paraxial effects. The analysis is performed by the hydrodynamic limit of the Schr\"odinger equation. The non-commutating variables in the… read more here.

Abstract: We experimentally realize three-dimensional non-paraxial accelerating beams associated with different coordinate systems. They are obtained by Fourier transforming a phase-modulated wave front in an aberration-compensated system. The phase pattern is encoded to include the phase… read more here.

Abstract: The simulation of large-area diffractive optical elements (DOEs) is challenging when non-paraxial propagation and coupling effects between neighboring structures shall be considered. We developed a novel method for the farfield simulation of DOEs, especially computer-generated… read more here.

Abstract: We propose a novel intensity diffraction tomography (IDT) reconstruction algorithm based on the split-step non-paraxial (SSNP) model for recovering the 3D refractive index (RI) distribution of multiple-scattering biological samples. High-quality IDT reconstruction requires high-angle illumination… read more here.
