An Asymmetric Star Design for the Dynamic Control of Quantum-Emitter-Coupled Plasmonic Nanoantenna Emission

Plasmonic single nanoantennas and metasurfaces can both enhance and manipulate emission from potential quantum emitters while their layer-like nano thick structure renders them integrable into quantum and nano-devices. Here we proposed an Asymmetric Star Nanoantenna design, which when coupled to a s...

Summary:Plasmonic single nanoantennas and metasurfaces can both enhance and manipulate emission from potential quantum emitters while their layer-like nano thick structure renders them integrable into quantum and nano-devices. Here we proposed an Asymmetric Star Nanoantenna design, which when coupled to a single quantum dot emitter, offered unique resonant enhancements in both single and array arrangements. This enhancement was most established with the array, where 3 main polarization tunable behavioral states were identified, ones we described as double, single and steady mode patterns. This polarization driven functionality could offer a much-needed means of control over quantum emitters.
