Recent advances in subwavelength photonic structures have stimulated growing attention to nonlocality that extends beyond a single unit cell. While flat optical devices such as metasurfaces are commonly described using local electromagnetic models, where each slit is assumed to respond independently to …

Ultrathin active materials are essential for compact nonlinear and quantum photonic devices, yet no general principle exists to link their optical constants to the cavity designs required for simultaneous field buildup and reflection suppression. Consequently, achieving extreme optical confinement currently relies on …

Broadband and omnidirectional antireflection is essential for maximizing the optical efficiency of silicon photodetectors. Conventional antireflection strategies─including graded-index multilayers and photonic crystal structures─can broaden spectral response; however, they typically require thick layer stacks that induce significant thermal and mechanical stress during integration …

Altermagnetism, a newly discovered magnetic phase, blends the beneficial properties of ferromagnetism and antiferromagnetism, spurring extensive efforts to utilize it for spintronic applications. The unique transport properties, when transplanted to photonic systems, are anticipated to offer a new degree of freedom for …

We present an efficient technique for enhancing the accuracy of near-to-far field (NTFF) transformations in the finite-difference time-domain (FDTD) method. By incorporating phase-shift FFT interpolation, our approach significantly improves the precision and reliability of far-field predictions based on simulated near-field data. The …
