Relation of Continuous Chirality Measure to Spin and Orbital Polarization, and Chiroptical Properties in Solids

Advanced Optical Materials, EarlyView.
This work quantifies chirality through the continuous chirality measure (CCM). The CCM is correlated to a variety of properties: spin‐orbit field, orbital angular momentum, circular dichroism, absorption dissymmetry factor (gCD) and the circular photogalvanic effect.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

Advanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Numerical Aperture Dependence of Mie Modes in Low Refractive Index Particles and Enhanced Collection Using Metallic Substrates

Advanced Optical Materials, EarlyView.
The influence of numerical aperture (NA) on the detection of Mie resonances in dielectric spheres is demonstrated. Experiments and simulations reveal that varying NA modifies mode amplitudes and linewidths. Furthermore, metallic substrates redirect modes toward low angles, enabling efficient mode detection with low NA optics and reducing perturbation ...

Multi‐Channel Quantum Dot Single‐Photon Sources on a Fiber‐Integrated Platform

Advanced Optical Materials, EarlyView.
A breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. By combining an optimal nanophotonic cavity, individual device transfer process, and integrated electrodes on a V‐groove fiber, the all‐fiber integrated system exhibits capabilities of low‐temperature cooling, efficient single‐photon transmission, selective ...

Polar Indirect Valley as a Limiting Factor for Radiative Efficiency in Gold‐Based Mixed‐Valence Double Perovskites

Advanced Optical Materials, EarlyView.
This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...
