Room temperature spin injection into commercial VCSELs at non-resonant wavelengths
Timur Almabetov, Petros Androvitsaneas, Zhongze Ren +3
Spin lasers leverage electron spin-polarisation to control photon polarisation, offering the potential for lower thresholds, rapid modulation, and all-optical data processing. We r…
Nanoring Tamm Cavity in the Telecommunications O band
Huili Hou, David Dlaka, Jon Pugh +2
Quantum and classical telecommunications require efficient sources of light. Semiconductorsources, owing to the high refractive index of the medium, often exploit photonic cavities…
Reflection by two level system: phase singularities on the Poincaré hypersphere
Ben Lang, Edmund Harbord, Ruth Oulton
We consider the reflection of a photon by a two-level system in a quasi-one-dimensional waveguide. This is important in part because it forms the backdrop for more complicated prop…
Perfect Chirality with imperfect polarisation
Ben Lang, Dara P. S. McCutcheon, Edmund Harbord +2
Unidirectional (chiral) emission of light from a circular dipole emitter into a waveguide is only possible at points of perfect circular polarisation (C points), with elliptical po…
A Tamm Plasmon-Porous GaN Distributed Bragg Reflector Cavity
Jon R. Pugh, Edmund Harbord, Andrei Sarua +4
This paper reports on design, measurement and optimisation of a Tamm plasmon metal-DBR cavity for use in the green part of the visible spectrum. It uses an optimised silver layer t…
A model for confined Tamm plasmon devices
Mike Adams, Ben Cemlyn, Ian Henning +3
It is shown that cavities formed between a multilayer quarter-wave Bragg reflector and a metal mirror which support Tamm plasmons can be modelled by using a hard-mirror approximati…
