Extremely confined gap plasmon modes: when nonlocality matters
Sergejs Boroviks, Zhan-Hong Lin, Vladimir A. Zenin +7
Historically, the field of plasmonics has been relying on the framework of classical electrodynamics, with the local-response approximation of material response being applied even…
Circular dichroism in nanoparticle helices as a template for assessing quantum-informed models in plasmonics
Christos Tserkezis, A. T. Mina Yeşilyurt, Jer-Shing Huang +1
As characteristic lengths in plasmonics rapidly approach the sub-nm regime, quantum-informed models that can capture those aspects of the quantum nature of the electron gas that ar…
Photoluminescence-driven Broadband Transmitting Directional Optical Nanoantennas
Kel-Meng See, Fan-Cheng Lin, Tzu-Yu Chen +4
Optical nanoantennas mediate near and far optical fields. Operating a directional nanoantenna in transmitting mode is challenging as the antenna needs to be driven by a nanosized o…
Slant-gap plasmonic nanoantenna for optical chirality enhancement
Daniel Lin, Jer-Shing Huang
We present a new design of plasmonic nanoantenna with a slant gap for optical chirality engineering. At resonance, the slant gap provides highly enhanced electric field parallel to…
