Summary: Quantum sensing is a branch of quantum science and technology that aims to measure physical quantities with high resolution, sensitivity, and dynamic range. In this study, the authors use electron spins in diamond as magnetic field sensors and couple them with a thin-film magnet to achieve broadband microwave detection. They exploit the non-linear spin-wave dynamics of the magnet to convert target microwave signals to the sensor-spin frequency and enable sensing and high-fidelity spin control over a gigahertz bandwidth.

Summary: Photonic skyrmions and merons are topological quasiparticles with nontrivial electromagnetic textures, which have great potential in manipulating light-matter interactions and deep-subwavelength imaging. In this study, the topological stability of photonic spin meron lattices is demonstrated by inducing a perturbation to break the C4 symmetry, revealing the metastability of photonic meron. The spin topology is verified through the interference of plasmonic vortices with a broken rotational symmetry, providing new insights into optical topological quasiparticles.

Summary: The high-order Poincare sphere introduces a mapping for representing vector beams with homogeneous ellipticity by a specific point on its surface. This study proposes a quantitative detection method for high-order Poincare sphere beams by introducing nonuniform polarization bases in the high-order Stokes parameters. The overall polarization detection is achieved by separating and measuring the intensity of different nonuniform polarization bases using an S-plate. The polarization evolution of the high-order Poincare sphere beams is demonstrated using the S-plate. These results provide new insights into the generation, evolution, and detection of arbitrary beams on the high-order Poincare sphere.

Summary: This study numerically analyzes the tightly focusing characteristics of higher-order spatiotemporal optical vortices (STOVs) and presents a method to dynamically modulate their transverse orbital angular momentum. The simulation results show that when the waist radius of the incident wave packet is larger than 40% of the pupil radius of the focusing lens, the higher-order STOVs split into two first-order vortices. The spacing of the split vortices can be tailored by adjusting the waist radius of the incident wave packet. The presented method provides a flexible way to engineer spatiotemporal vortices in tightly focused wave packets.

Summary: We demonstrate a cascaded mode converter composed of q-plates and half waveplates for generating high-order Poincare sphere (HOPS) beams of different orders. The converter enables reliable and switchable generation of multiple HOPS beams with exponential growth in the available number of orders. The local polarization state and order of the HOPS beams can be used as two degrees of freedom to encode 2 bits of information. This method opens up possibilities for generating multiple and ultrahigh order Poincare sphere beams, with potential applications in communication systems.

Summary: In this work, a diffractive circular dichroism enhancement technique using stereoscopic plasmonic molecule structures is proposed. The dominant chiral scattering mechanism is identified as the z-component of the electric dipole during the interaction between an individual plasmonic molecule and a grazing plane wave. Through the design of periodic plasmonic molecule structures, large diffractive circular dichroism can be achieved, which is validated by numerical simulations and experimental results. The proposed approach has potential application in enhanced spectroscopy techniques for measuring chiral information, crucial for fundamental physical and chemical research as well as bio-sensing applications.

Summary: This study proposes a general incoherent modal decomposition method for partially coherent light fields and demonstrates its feasibility through experimentation. The method can be used to reconstruct average intensity, cross-spectral density, and orthogonal decomposition properties of partially coherent light fields, revealing the invariance of light fields and retrieving embedded information after propagation through complex media. Examples of Gaussian-shell-model beam and partially coherent Gaussian array are used to demonstrate the reconstruction and even prediction of second-order statistics. This method is expected to pave the way for applications of partially coherent light in optical imaging, optical encryption, and antiturbulence optical communication.
