Long-Lived Coherent Acoustic Phonons in Epitaxially Grown III-V Adiabatic Cavities
Muhammad Hanif, Milos Dubajic, Sandeep. J. Sreerag +4
We provide evidence of strongly confined coherent acoustic phonons inside high quality factor phononic cavities that exhibit tailoredphonon potentials. Using GaAs/AlAs quasiperiodi…
Acceleration and adiabatic expansion of multi-state fluorescence from a nanofocus
Nicholas A. Güsken, Ming Fu, Maximilian Zapf +7
Since Purcell's seminal report 75 years ago, electromagnetic resonators have been used to control light-matter interactions to make brighter radiation sources and unleash unprecede…
Singlet Fission Photovoltaics: Progress and Promising Pathways
Alexander J. Baldacchino, Miles I. Collins, Michael P. Nielsen +3
Singlet fission is a form of multiple exciton generation which occurs in organic chromophores when a high energy singlet exciton separates into two lower energy triplet excitons, e…
Identifying optimal photovoltaic technologies for underwater applications
Jason A. Röhr, Ed Sartor, Joel N. Duenow +12
Improving solar energy collection in aquatic environments would allow for superior environmental monitoring and remote sensing, but the identification of optimal photovoltaic techn…
Optoelectronic Reciprocity in Hot Carrier Solar Cells with Ideal Energy Selective Contacts
Andreas Pusch, Milos Dubajic, Michael P. Nielsen +3
Hot carrier solar cells promise theoretical power conversion efficiencies far beyond the single junction limit. However, practical implementations of hot carrier solar cells have l…
Singlet fission and tandem solar cells reduce thermal degradation and enhance lifespan
Y. Jiang, M. P. Nielsen, A. J. Baldacchino +5
The economic value of a photovoltaic installation depends upon both its lifetime and power conversion efficiency. Progress towards the latter includes mechanisms to circumvent the…
Hybrid plasmonic waveguide coupling of photons from a single molecule
Samuele Grandi, Michael P. Nielsen, Javier Cambiasso +7
We demonstrate the emission of photons from a single molecule into a hybrid gap plasmon waveguide (HGPW). Crystals of anthracene, doped with dibenzoterrylene (DBT), are grown on to…
Efficient four-wave mixing at the nanofocus of integrated organic gap plasmon waveguides on silicon
Michael P. Nielsen, Xingyuan Shi, Paul Dichtl +2
Nonlinear optics, especially frequency mixing, underpins modern optical technology and scientific exploration in quantum optics, materials and life sciences, and optical communicat…
