Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

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.

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 ...
