Design and Simulation of a Nanophotonic Traceable Memory Using Localized Energy Dissipation and Hierarchy of Optical Near-Field Interactions

Abstract

Optical near-field interactions allow energy localization at scales smaller than the diffraction limit of light. They also show intrinsic hierarchical responses, meaning that optical nearfields exhibit different physical behavior at different scales. In this paper, by combining the localized energy dissipation and hierarchy properties, we present an architecture for a novel traceable optical memory that records memory access events to each bit, which is useful in applications such as high-security information transfer. The basic principles are demonstrated by numerical simulations using a metal nanostructure.

Dressed photon technology

“…Shape-engineering of metal nanostructures is a promising asset in realizing hierarchical optical responses thanks to the progress of technologies in fabricating fi ne nanostructures [82,83] . Optical near-and far-fi eld responses from metal nanostructures can be understood in a unifi ed manner by examining induced electric currents in individual nanostructures and their associated DP-CPs between the nanostructures [84] .…”

System architectures for nanophotonics for information and communications applications

“…Optical near-fields behave differently depending on the physical scales involved [1,3]. They have been applied to various applications such as information and communications devices and systems [1,7] and nano-fabrications [8]. Technological vehicles for such architectures include shape-engineered nanostructures [7], quantum nanostructures [9], and many others.…”

Hierarchy in Optical Near-fields by Nano-scale Shape Engineering and its Application to Traceable Memory

“…We have also discussed the theoretical origin of the hierarchy using a dipole-based model and have considered possible vulnerability associated with polarization dependence. We will further investigate the hierarchical nature in optical near-fields, for example, based on angular-spectrum analysis, 11) and we will pursue experimental techniques, for instance, by employing quantum dot structures 13,20) in addition to shape-engineering of metal nanostructures.…”
