Journal ArticleDOI
Nanodot coupler with a surface plasmon polariton condenser for optical far/near-field conversion
TL;DR: In this paper, a nanodot coupler was fabricated from a linear array of closely spaced metallic nanoparticles to increase the optical far-to-near-field conversion efficiency for transmission.
Journal ArticleDOI
Realization of an ultra-flat silica surface with angstrom-scale average roughness using nonadiabatic optical near-field etching
TL;DR: In this paper, a nonadiabatic process is applied to a synthetic silica substrate using a continuum wave laser (λ=532 nm) with a Cl2 gas source, where the absorption band edge energy of Cl2 is higher than the photon energy of the light source.
Journal ArticleDOI
Self-assembly of size- and position-controlled ultralong nanodot chains using near-field optical desorption.
TL;DR: Self-assembly of a size- and position-controlled ultralong nanodot chain using a novel effect of near-field optical desorption is reported, allowing one to increase the throughput of the production of nanoscale structures dramatically at all scales.
Journal ArticleDOI

TL;DR: In this article, the authors demonstrate the ability to solve a decision-making problem on the basis of optical excitation transfer via near-field interactions by using colloidal quantum dots of different sizes, formed on a geometry-controlled substrate.
Journal ArticleDOI
Hierarchy in optical near-fields and its application to memory retrieval
TL;DR: Using the intrinsic logical hierarchy of information and a simple digital coding scheme, scale-dependent optical memory accesses are associated with different levels of the information hierarchy.
