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…

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…

Genetically encoding stimulated Raman-scattering probes for cell imaging using infrared fluorescent proteins

David Regan, Ozan Aksakal, Athena Zitti +8

Stimulated Raman scattering (SRS) microscopy offers great potential to surpass fluorescent-based approaches, owing to the sharp linewidth of Raman vibrations amenable to super-mult…

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…
