Logical Fallacy of using the Electric Field in Non-resonant Near-field Optics
Itsuki Banno, Motoichi Ohtsu
We find that the electric field is not a suitable physical quantity to describe the response of a non-metallic material in the study of non-resonant near-field optics. In practice,…
Randomness in highly reflective silver nanoparticles and their localized optical fields
Makoto Naruse, Takeharu Tani, Hideki Yasuda +3
Reflection of near-infrared light is important for preventing heat transfer in energy saving applications. A large-area, mass-producible reflector that contains randomly distribute…
Chaotic oscillation and random-number generation based on nanoscale optical-energy transfer
Makoto Naruse, Song-Ju Kim, Masashi Aono +2
By using nanoscale energy-transfer dynamics and density matrix formalism, we demonstrate theoretically and numerically that chaotic oscillation and random-number generation occur i…
Unidirectional light propagation through two-layer nanostructures based on optical near-field interactions
Makoto Naruse, Hirokazu Hori, Satoshi Ishii +7
We theoretically demonstrate direction-dependent polarization conversion efficiency, yielding unidirectional light transmission, through a two-layer nanostructure by using the angu…
Analysis of optical near-field energy transfer by stochastic model unifying architectural dependencies
Makoto Naruse, Kouichi Akahane, Naokatsu Yamamoto +4
We theoretically and experimentally demonstrate energy transfer mediated by optical near-field interactions in a multi-layer InAs quantum dot (QD) structure composed of a single la…
Decision making based on optical excitation transfer via near-field interactions between quantum dots
Makoto Naruse, Wataru Nomura, Masashi Aono +5
Optical near-field interactions between nanostructured matter, such as quantum dots, result in unidirectional optical excitation transfer when energy dissipation is induced. This r…
High-power doughnut beam generation for atom-funnel experiment
S. M. Iftiquar, H. Ito, K. Totsuka +2
We have generated high power doughnut beam suitable for atom funnel experiment with the conversion efficiency of about 50 %.
Excitation Of A Funnel-Shape Optical Near Field By The Laguarre-Gaussian Doughnut Beam
S. M. Iftiquar, Haruhiko Ito, Akifumi Takamizawa +1
Optical near field has been generated by Laguarre-Gaussian doughnut beam on inner surface of "atom funnel". The resulting optical near field has been measured with the help of fibe…
