This study bridges the gap between theory and experiment in 2D nanophotonics by demonstrating momentum-resolved reflectivity measurements on 5-μm-thick photonic crystals that align excellently with 2D theoretical calculations and simulations, thereby validating experimental methods for the near-infrared telecom range.
This paper presents a deep learning framework that corrects optical distortions in electron diffraction patterns without requiring calibration samples or prior knowledge of the reciprocal lattice, achieving superior accuracy over conventional methods for medium and large disk patterns while enhancing experimental ptychographic reconstructions.
This paper demonstrates that the propagation dynamics of spatiotemporal Laguerre-Gaussian modes in isotropic dispersive media are governed by SU(2) symmetry and a conserved Gouy phase, which explains multi-petal far-field patterns and reveals a phase-locked revival mechanism in anomalous dispersion analogous to the Talbot effect.
This paper presents a real-time, all-fiber microendoscopic polarization sensor that achieves single-photon-level accuracy and complete state reconstruction in constrained, low-light environments by utilizing a few-mode fiber coupled with a deep-learning-based calibration neural network.
This study reports the observation of significant cubic magneto-optic Kerr effect (CMOKE) contributions in Co(111) thin films, demonstrating that these third-order effects can dominate over linear MOKE at normal incidence and must be accounted for to correctly interpret magneto-optic data.
This study introduces a unified static-limit formulation to compare two scissors-correction schemes for calculating second-harmonic generation in ultraviolet nonlinear-optical crystals, revealing that while both preserve spectral shapes, scheme-N yields systematically larger magnitudes and that apparent violations of Kleinman symmetry in practice stem from sum-rule approximations rather than the underlying theory.
This study demonstrates that the interplay between four-wave mixing and cascade Brillouin lasing in coherently driven passive optical-fibre resonators spontaneously generates highly stable, paracrystalline patterns of temporal cavity solitons locked by long-range acoustic oscillations, a phenomenon accurately described by a unified mean-field model.
