Nanohotonic traceable memorybased onener loca ization andhierarch ofoptical near-elds

Optical near-field interactions allowenergy applications suchas high-secLuity informaion transfer localization atscales smaller thanthediffraction limit oflight.(confidentiality couldbe ensured) or managing data Theyalsoshowhierarchical responses, meaning thatopticaldistribution incontent delivery (thedistribution ofdigital near-fields exhibit different physical behavior atdifferent scales.content could bephysically recorded). Inthis paper, bycombining these properties ofoptical near-fields, thatis,energy-localizat ion andhierarchy, wepresent anovel Thispaper isorganized asfollows. InSection II, wediscuss traceable optical memorythatrecords theevent ofmemory thebasic physical principles oftraceable memory. InSection access toeachofthebits, which isuseful inapplications suchas III, wedemonstrate anexample using ametalnanostructure high-security information transfer. Thebasicprinciple is modeled byfinite difference timedomainsimulations. We numerically demonstrated using ametal nanostructure. conclude thepaper inSection IV.
