Nanoscale Fluorescence Thermometry: Probes, Recent Advances and Emerging Directions
Md Shakhawath Hossain, Nhat Minh Nguyen, Thi Ngoc Anh Mai +10
The transition of materials and devices to nanometer, atomic, and quantum scales makes thermal characterization increasingly challenging, driving the need for advanced nanoscale th…
Generalized Non-Hermitian Hamiltonian for Guided Resonances in Photonic Crystal Slabs
Viet Anh Nguyen, Hung Son Nguyen, Zhiyi Yuan +6
We develop a generalized non-Hermitian Hamiltonian formalism for guided resonances in photonic crystal slabs, derived directly from Maxwell's equations through a systematic guided-…
Micrometer-resolution fluorescence and lifetime mappings of CsPbBr nanocrystal films coupled with a TiO grating
Viet Anh Nguyen, Linh Thi Dieu Nguyen, Thi Thu Ha Do +15
Enhancing light emission from perovskite nanocrystal (NC) films is essential in light-emitting devices, as their conventional stacks often restrict the escape of emitted light. Thi…
Direct Observation of Exceptional Points in Photonic Crystal by Cross-Polarization Imaging in Momentum Space
Viet Anh Nguyen, Viet Hoang Le, Loïc Malgrey +8
This study explores exceptional points (EPs) in photonic crystals (PhCs) and introduces a novel method for their single-shot observation. Exceptional points are spectral singularit…
Coexistence of Surface Lattice Resonances and Bound states In the Continuum in a Plasmonic Lattice
Quoc Trung Trinh, Sy Khiem Nguyen, Dinh Hai Nguyen +4
We present a numerical study on a 2D array of plasmonic structures covered by a subwavelength film. We explain the origin of surface lattice resonances (SLRs) using coupled dipole…
Enhanced Delayed Fluorescence in Tetracene Crystals by Strong Light-Matter Coupling
Matthijs Berghuis, Alexei Halpin, Quynh Le-Van +4
We demonstrate experimentally an enhanced delayed fluorescence in tetracene single crystals strongly coupled to optical modes in open cavities formed by arrays of plasmonic nanopar…
Unified Weak-to-Strong Coupling Transitions and Radiation Interference Induced by Vertical-Symmetry Breaking in Photonic Crystal Slabs
Huy Hoang Chu, Raphael Mermet-Lyaudoz, Florian Dubois +10
Vertical-symmetry breaking provides a versatile means of coupling leaky photonic-crystal resonances that are otherwise protected by opposite out-of-plane parity. Here, we develop a…
Screened Strong Coupling of Excitons in Multilayer WS2 with Collective Plasmonic Resonances
Shaojun Wang, Quynh Le-Van, Fabio Vaianella +5
We demonstrate the strong coupling of direct transition excitons in tungsten disulfide (WS2) with collective plasmonic resonances at room temperature. We use open plasmonic cavitie…
