Directional Lasing from a 3D Blue Phase Photonic Crystal
This work presents the first directional lasing from millimeter‐scale monocrystalline 3D photonic crystals, specifically Blue Phases (BPs), overcoming prior limitations of random lasing in polycrystals. These 3D soft photonic crystals enable highly directional, circularly polarized, mirrorless lasing via resonant polarization modes, offering the ...

Flat Optics for Polarization Structure Engineering from 2D to 3D
Metasurfaces have transformed polarization control by enabling precise engineering of complex polarization structures. This review explores their evolution from generating 2D polarization structures to shaping fully 3D polarization fields. By unlocking the unprecedented control over the polarization and spectral information of light, these advances ...

A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
