Ultra-high-speed line-scan Raman imaging
Qingyi Wu, Xusheng Tang, Francesco Masia +7
Raman spectroscopic imaging has emerged as a potent tool due to its non-invasive nature and capability for chemical composition analysis. Line-scan Raman spectroscopy accelerates i…
The origin and influence of non-cavity modes in a micropillar Bragg microcavity
Matthew Jordan, Wolfgang Langbein, Anthony J. Bennett
Controlling the photonic environment of emitters is essential to the design of classical and quantum light sources. We study the case of a dipole-like emitter in a cylindrical pill…
Exciton coherence propagation measured with non-local four-wave mixing micro-spectroscopy
Mateusz Raczyński, Amadeusz Dydniański, Karolina Ewa Połczyńska +8
Coherence transfer is a multi-disciplinary topic of interest, including chemistry, biology and physics. In quantum technologies, achieving non-local coherent coupling between solid…
Designing low-loss cavities across the band-gap of photonic crystal slabs
Nadhia Monim, Wolfgang Langbein, Francesco Masia
Photonic crystal cavities (PCCs) are defects in host photonic crystals (PCs) which create bound states in the PC band gap. These bound states are resonant states of the electromagn…
Sub-nanometer 3D morphometric precision of polarisation-resolved wide-field optical extinction microscopy determines the roundness of individual gold nanospheres
Lukas M Payne, Furqan Alabdullah, Paola Borri +1
Quantitative polarisation-resolved optical extinction microscopy of individual plasmonic nanoparticles has recently been introduced as a powerful tool to characterise the nanoparti…
Extending completeness of the eigenmodes of an open system beyond its boundary, for Green's function and scattering-matrix calculations
Zoltan Sztranyovszky, Wolfgang Langbein, Egor Muljarov
The asymptotic completeness of a set of the eigenmodes of an open system with increasing number of modes enables an accurate calculation of the system response in terms of these mo…
Thousand foci coherent anti-Stokes Raman scattering microscopy
Dominykas Gudavicius, Lukas Kontenis, Wolfgang Langbein
We demonstrate coherent anti-Stokes Raman scattering (CARS) microscopy with 1089 foci, enabled by a high repetition rate amplified oscillator and optical parametric amplifier. We e…
Quantitatively linking morphology and optical response of individual silver nanohedra
Yisu Wang, Zoltan Sztranyovszky, Attilio Zilli +4
The optical response of metal nanoparticles is governed by plasmonic resonances, which are dictated by the particle morphology. A thorough understanding of the link between morphol…
Resonant state expansion applied to three-dimensional open optical systems
M. B. Doost, W. Langbein, E. A. Muljarov
The resonant state expansion (RSE), a rigorous perturbative method in electrodynamics, is developed for three-dimensional open optical systems. Results are presented using the anal…
