Complex Structured Light Generation Using Printed Liquid Crystal Droplets

Advanced Optical Materials, EarlyView.
Inkjet‐printed liquid crystal droplets generate structured light beams with spatially varying polarization and phase. These include full Poincaré beam, vortex beam carrying orbital angular momentum, and beam with polarization singularities, offering a simple approach for compact structured light generation in optical manipulation, imaging, and ...

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems

Advanced Optical Materials, EarlyView.
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, EarlyView.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

Effects of Extreme Mirror Downscaling on Open Micro‐Fabry–Perot Spectral Responses and Resonant Mode Profiles

Advanced Photonics Research, EarlyView.
Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities

Strong Resonant Enhancement in Polarization Anisotropy in Third Harmonic Generation from MoS2 Disks with Subtle Structural Ellipticity

Advanced Photonics Research, EarlyView.
Strong resonant amplification in polarization anisotropy in third harmonic generation (THG) response from isolated MoS2 disks with small structural ellipticity introduced during fabrication is reported. This is attributed to the high refractive index of the MoS2 disk that supports characteristic anapole resonances combined with the cubic dependence of ...
