Summary: In this work, dynamically switchable metasurfaces based on vanadium dioxide are presented, achieving state switching of reflected wavefront for circularly polarized wave in the terahertz band. Phase modulation is achieved by rotating the vanadium dioxide strip, and the phase transition between metallic and insulating states enables the design of applications such as gradient metasurfaces, vortex beam generators, and reflective lenses with switchable focusing function.

Summary: A new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface is proposed in this paper. By superimposing the responses of two types of meta-atoms, several typical polarization states for linearly polarized waves can be efficiently evolved, providing a new idea for the design of terahertz multi-functional metadevices.

Summary: The rapid development of artificial material designing and nanoprocessing technology has greatly facilitated the growth of novel planar optical devices. Traditional optical phase gradient devices face limitations in scaling down size, so new strategies are needed. In this study, we develop a series of novel compact planar devices using the superpositionable, polarization-dependent properties of the Pancharatnam-Berry phase. Our compact devices, made of well-designed dielectric glass plates, offer a new and simple solution to transmission loss in a cascade system of phase gradient devices.

Summary: This article introduces the geometric phase of classical electromagnetic light beams, which is applicable to fields undergoing cyclic, discrete polarizations changes. Berry later recognized a similar phase for adiabatic quantum systems, extending it to nonadiabatic and noncyclic quantum state evolutions. However, no optical counterpart for the noncyclic, adiabatic evolution has been demonstrated. In this study, a modified Young's two-pinhole setup is used to generate arbitrary continuous spatial evolution of polarization state, demonstrating the adiabatic noncyclic evolution of the Pancharatnam-Berry phase in an optical context.

Summary: A wide class of singular inhomogeneously polarized beams with nonuniform rotation rate of polarization azimuth are introduced in this study. They are obtained by adding extra phase modulation with m-fold rotational symmetry to the helical wavefronts of Poincare beams. The modulated Poincare beams have been theoretically studied and experimentally generated using tailored space-varying-axis plates based on liquid crystals.

Summary: This paper investigates the analogy between the topological properties of Hofstadter Hamiltonians and the diffraction figures resulting from optical gratings. By establishing a one-to-one relation between Diophantine equations and the Bragg condition, the influence of structural disorder on the robustness of diffraction figures in optical gratings is discussed, which can be analogous to the robustness of transverse conductance in the quantum Hall effect.

Summary: The authors introduce a new optical encoding technique called linear photonic gears, which enables ultra-sensitive measurements of transverse displacements by mapping them into the polarization rotation of a laser beam. They argue that a resolution of 50 pm should be achievable with existing state-of-the-art technologies.

Summary: In this paper, we report the discrete-time quantum walk of two correlated photons in a two-dimensional lattice. The lattice is synthetically engineered by manipulating optical modes and mode-coupling is introduced via diffractive action of optical elements. The platform is compact, efficient, and scalable, making it a versatile tool for simulating quantum evolutions on complex lattices.
