Fast Simulation of Wide‐Angle Coherent Diffractive Imaging

Laser &Photonics Reviews, EarlyView.
The propagation multi‐slice Fourier transform method is introduced as an accurate and efficient approach for describing light scattering for arbitrarily shaped objects. Its exceptional suitability for simulating coherent diffractive imaging of nanoparticles in the XUV and soft X‐ray range is demonstrated.

Sensitivity‐Tunable Complex Permittivity Sensing Enabled by Bound States in the Continuum in a Waveguide‐Resonator System

Laser &Photonics Reviews, EarlyView.
This work introduces two types of bound states in the continuum (BICs) and their merging in a waveguide‐resonator system, which significantly enhances the quality factor (Q$Q$). Benefiting from the high‐Q$Q$ characteristics of quasi‐BICs, a sensitivity‐tunable complex permittivity sensor is developed based on this system, achieving improvements of 93 ...

Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing

Laser &Photonics Reviews, EarlyView.
This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,

Topological Photonic Devices and Circuits at Terahertz Frequencies

Laser &Photonics Reviews, EarlyView.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.
