Geometric Phase and Spinor Beam Dynamics of Paraxial Beams
We show that treating a paraxially propagating electric field as a spinor provides a natural way to include geometric phase in beam propagation models.Inline inter-core phase control in multi-core fiber with a commercial polarization controller
Inter-core phase control is a prerequisite for interferometry in multi-core fiber (MCF), but no compact inline element for this purpose is presently available, and existing approaches require fanout…Axion polarimetry with parametric readout: photon-number conversion and sensitivity limits
We propose a bias-assisted active photon-number conversion scheme for axion-induced polarization rotation in a four-port optical ring cavity with parametric readout.Coherent 1-μm-Band Co-Transmission with C+L-Band Channels over 50-km Hollow-Core Fiber
We experimentally demonstrate simultaneous coherent transmission across 1-$μ$m and C+L bands, carrying $54\times125$-GBaud PDM-16QAM C+L channels and $2\times15$-GBaud PDM-QPSK 1-$μ$m channels over…Aberration stabilized light bullets in normal dispersion injected Kerr resonators
We investigate three-dimensional light bullets (LBs) in an optically injected, vertically emitting Kerr-Gires-Tournois interferometer operating in the normal dispersion regime.Single-pass stochastic cooling for electron microscopy
Scientific applications of free electrons, such as in electron microscopes and particle accelerators, are limited by the brightness of available electron sources.Ray propagation of circularly polarized light in an inhomogeneous medium: the optical Magnus effect from Maxwell's equations
We derive the ray propagation of circularly polarized light in an inhomogeneous, isotropic and lossless medium, including the first correction to geometrical optics, the optical Magnus (spin Hall)…Pump quantization changes optimal measurements for quantum sensing
Standard analyses of quantum phase sensing often neglect the overhead of generating squeezed-light by treating the pump as an undepleted classical resource.Contrast-Enhanced Nonlinear Imaging with Moiré Flatband Superlattices
Nonlinear metasurfaces offer a compact platform for infrared-to-visible conversion and imaging, yet resonant enhancement is often accompanied by restricted angular acceptance, limiting the range of…Reconfigurable multi-tone mmWave/THz generation powered by high-efficiency Kerr parametric oscillation
Broadband and simultaneously accessible multi-tone millimeter-wave (mmWave) and terahertz (THz) signals are attractive for multi-band wireless communication and spectroscopy applications, yet their…PETE: A Hybrid Photonic and Electronic Thermoelectric Device for Direct Heat-to-Electricity Conversion
Photonic heat engines can achieve high conversion efficiencies, but their far-field power density is constrained by the blackbody limit.From Rock Tumbling to Telescope Mirror Grinding: How Optical Perfection Emerges from Random Motion
When two glass disks are rubbed together by hand with an abrasive between them, their surfaces spontaneously converge to perfectly matching spherical curves, accurate to tens of nanometers.Learned optical compression for single-pixel quantitative phase imaging
Quantitative phase imaging (QPI) reveals optical path-length variations in transparent objects but typically relies on spatially resolved intensity measurements.Self-driven beta-radiation detection through a graphene/water/silicon heterostructure
Large-volume neutrino observatories, exemplified by IceCube, exploit Cherenkov light generated by neutrino-induced charged particles in Antarctic ice, highlighting the potential of water-based media…Spin-induced lateral acoustic forces on chiral and achiral particles
Acoustic spin enables intriguing chiral sound-matter interactions, yet its mechanical consequences remain much less explored.Propagation invariant one-dimensional flat-top vector beam with conserved topology
We report the generation and control of a propagation invariant one-dimensional flat-top vector beam through the digitally controlled superposition of a first-order petal- and Gaussian- mode each…Experimental demonstration of phase-conjugated twin-wave coherent reception over 100 km with injection locking assisted phase stabilization
Recovering complex optical signals with high sensitivity is central to coherent communication and sensing.Seeing Why: Exact Evidence Maps for Quantum and Optical Image Classifiers
When an image classifier decides, we can usually only estimate why.Controlling the Sign and Magnitude of the Thermoreflectance Coefficient of Gold-MoS$_2$ Metamaterials
Heating a material changes how much light it reflects.Scan-less Hyperspectral Polarimetric Imaging Using Dual-Comb Single-Pixel Imaging
Spectroscopic polarimetry enables detailed characterization of light-matter interactions by combining spectral and polarization information, yet conventional implementations rely on mechanical…
