Time diffraction of optical helicity
Alex J. Vernon, Jingyi Wu, Anton Y. Bykov +4
If in a classic double-slit interference experiment the light that passes though one slit is in an orthogonal polarisation state to that of the second slit, no visible interference…
Ultrafast cascade charge transfer in multi bandgap colloidal quantum dot solids enables threshold reduction for optical gain and stimulated emission
Nima Taghipour, Mariona Dalmases, Guy Luke Whitworth +2
Achieving low-threshold infrared stimulated emission in solution-processed quantum dots is critical to enable real-life application including photonic integrated circuits (PICs), L…
Colloidal quantum dot infrared lasers featuring sub-single-exciton threshold and very high gain
Nima Taghipour, Mariona Dalmases, Guy L. Whitworth +3
The use of colloidal quantum dots (CQDs) as a gain medium in infrared laser devices has been underpinned by the need for high pumping intensities, very short gain lifetimes and low…
Low-threshold, highly stable colloidal quantum dot short-wave infrared laser enabled by suppression of trap-assisted Auger recombination
Nima Taghipour, Guy L. Whitworth, Andreas Othonos +5
Pb-chalcogenide colloidal quantum dots (CQDs) are attractive materials to be used as tuneable laser media across the infrared spectrum. However, excessive nonradiative Auger recomb…
A self-assembled two-dimensional thermo-functional material for radiative cooling
Juliana Jaramillo-Fernandez, Guy Luke Whitworth, Jose Angel Pariente +4
The regulation of temperature at the macro and microscale is a major energy-consuming process of humankind. Modern cooling systems account for 15% of the global energy consumption…
Terahertz emission by diffusion of carriers and metal-mask dipole inhibition of radiation
M. E. Barnes, D. McBryde, G. J. Daniell +7
Terahertz (THz) radiation can be generated by ultrafast photo-excitation of carriers in a semiconductor partly masked by a gold surface. A simulation of the effect taking into acco…
