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…
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…
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 RaczyÅski, Amadeusz DydniaÅski, Karolina Ewa PoÅczyÅska +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…
Understanding the mechanisms of supported lipid membrane reshaping into tubular networks using quantitative DIC microscopy
David Regan, Paola Borri, Wolfgang Langbein
Biological membranes are known to form various structural motifs, from lipid bilayers to tubular filaments and networks facilitating e.g. adhesion and cell-cell communication. To u…
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…
