Optics Papers of the Week

However, prior works describe this emergent effect using phenomenological models that fail to uncover its microscopic quantum origins, and as a result, a rigorous connection between material electronic structure and the optical SOI remains elusive. In this work, we address this fundamental challenge by developing a microscopic quantum theory starting from the non-relativistic quantum electrodynamical (QED) description of light-matter interactions.

We develop a common framework for classical simulation of boson and fermion sampling under thermal loss, including pure loss.

Topological transformations of their band structure can give rise to flatbands, which host dispersionless states with quenched kinetic energy and vanishing group velocity. Here we show that structuring ReS 2 into a resonant metasurface reshapes its photonic band topology, splitting the integer topological charge of the quasi-bound states in the continuum into two half-integer polarization singularities and driving the formation of directional far-field flatbands.

This work highlights the synergistic A‐site cation and halogen engineering of copper(I) halides for advanced x‐ray imaging scintillators.

This review provides a unified perspective on QD‐CCLs by integrating advances across QD materials (Cd‐based, perovskite, and heavy‐metal‐free systems), device architectures, and mechanically deformable platforms.

Recently, we presented interferometric nanoparticle tracking analysis (iNTA) as a highly sensitive label-free technique that is capable of determining the size, concentration, and index of refraction of different subpopulations in a suspension mixture.

This paper demonstrates the use of fiber Bragg gratings (FBGs) to measure internal temperature fields at high spatial resolution in difficult-to-access locations.

In this work, we experimentally investigate the astigmatism induced by a birefringent crystal inside an optical cavity and demonstrate a geometric compensation strategy for structured modes carrying orbital angular momentum (OAM).

In this work, we present an in-situ, non-destructive optical methodology to determine the CTE of suspended nanofilms by tracking the temperature-dependence of their vibrational frequency.
