Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Non‐Uniform Programmable Photonic Waveguide Meshes
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator
This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐
