Controlling the Coupling Strengths in Nanophotonic Networks using Modified Yagi-Uda Nanoplasmonic Antennas
Vidar Flodgren, Anders Mikkelsen
On-chip communication in optical neural networks is commonly done via waveguides which results in large system footprints. A compact alternative is to broadcast light signals betwe…
Self-selective growth of GaAs1-xBix on GaAs zinc blende/wurtzite nanowire heterostructures
Rohit Yadav, Sebastian Lehmann, Vidar Flodgren +5
Site-selective nanostructure growth and material incorporation at the atomic scale offer a promising pathway for engineering quantum materials and nanodevices. Here, GaAs nanowires…
Nanoscale photonic neuron with biological signal processing
Joachim E. Sestoft, Thomas K. Jensen, Vidar Flodgren +8
Computational hardware designed to mimic biological neural networks holds the promise to resolve the drastically growing global energy demand of artificial intelligence. A wide var…
Few-cycle lightwave-driven currents in a semiconductor at high repetition rate
Fabian Langer, Yen-Po Liu, Zhe Ren +9
When an intense, few-cycle light pulse impinges on a dielectric or semiconductor material, the electric field will interact nonlinearly with the solid, driving a coherent current.…
