As the second example, photonic fabrication systems demand drastic decreases in the size of the fabricated patterns for assembling ultra-large- scale integrated circuits. These requirements cannot be met even if the sizes of the materials are decreased by advanced methods based on nanotechnology. It is essentialto decreasethe size ofthe electromagneticfield usedas a carrierforsig- nal transmission, processing, and fabrication. Such a decrease in the size of the electromagnetic field beyond the diffraction limit of the propagating field can be realized in opticalnear fields. Nanophotonics,a novelopticaltechnologythat uti- lizes the optical near field, was proposed by Ohtsu (the editor of this monograph series)in1993tomeettheserequirements.However,itshouldbenotedthatthetrue nature of nanophotonics involves not only its ability to meet the above require- ments, but also its ability to realize qualitative innovations in photonic devices, fabricationtechniques, energyconversion,and informationprocessing systems by utilizingnovelfunctionsandphenomenamadepossiblebyopticalnear-fieldinter- actions, which are otherwise impossible as long as conventionalpropagatinglight isused.Basedoninterdisciplinarystudiesoncondensed-matterphysics,opticalsci- ence, and quantum field theory, nano-materials and optical energy transfer in the nanometricregimehavebeenextensivelystudiedinthelasttwodecades.Through thesestudies,noveltheoriesonopticalnearfieldshavebeendeveloped,andavariety ofnovelphenomenahavebeenfound.Theresultsofthisbasicresearchhavebeen appliedtodevelopnanometer-sizedphotonicdevices,nanometer-resolutionfabrica- tion,highlyefficientenergyconversion,andnovelinformationprocessing,resulting inqualitativeinnovations.Furtheradvancementintheseareasisexpectedtoestab- lishnovelopticalsciencesinthenanometricspace,whichcanbeappliedtofurther progressinnanophotonicstosupportthesustainabledevelopmentofpeoples’lives allovertheworld.ThisuniquemonographseriesentitledProgressinNanophoton- icsintheSpringerSeriesinNano-opticsandNanophotonicsisbeingintroducedto reviewtheresultsofadvancedstudiesinthefieldofnanophotonicsandcoversthe mostrecenttopicsoftheoreticalandexperimentalinterestinrelevantfields,suchas v vi PrefacetoProgressinNanophotonics classicalandquantumopticalsciences,nanometer-sizedcondensedmatterphysics, devices, fabrication techniques, energy conversion, information processing, archi- tectures,andalgorithms.Eachchapteriswrittenbyleadingscientistsintherelevant field. Thus, this monograph series will provide high-quality scientific and techni- calinformationto scientists, engineers,and studentswho are andwill be engaged innanophotonicsresearch.Ascomparedwiththepreviousmonographseriesenti- tled Progress in Nano-Electro-Optics (edited by Ohtsu, published in the Springer Series in Optical Science), this monograph series deals not only with optical sci- ence on the nanometerscale, butalso its applicationsto technology.I am grateful toDrAscheronofSpringer-Verlagforhisguidanceandsuggestionsthroughoutthe preparationofthismonographseries. Tokyo MotoichiOhtsu January2011 Preface This volume contains six review articles focusing on variousbut mutually related topics in nanophotonics written by the world’s leading scientists. Chapter 1 describes the concept of the dressed photon and its applications to qualitatively innovativeopticaldevices,fabricationtechniques,energyconversion,andsystems. Chapter 2 is devoted to describing basic concepts necessary for two-dimensional parallel processing of light–matter interactions on the nanometer scale to realize probe-freenanophotonicsystems.Additionally,theconceptsandsomedemonstra- tions of the hierarchy inherent in nanophotonics, based on the hierarchy between optical near- and far-fields, are describedas practicalapplicationsof opticalnear- field interactions. Chapter 3 describes self-organized fabrication of composite semiconductor quantum dots, which can be exploited for size- and position- controlled quantum dots for novel nanophotonic devices. Chapter 4 is devoted to near-field spectroscopy of metallic nanostructures, particularly visualization of plasmon wave functions and optical fields using near-field methods. Chapter 5 concerns simple experimentalapproachesfor constructing metallic nanoarrayson asolidsurfaceforapplicationstominiaturizedopticaldevices,sensors,andsingle- moleculedetection.Fortheseapplications,theauthordescribesauniqueapproach forfabricatingone-dimensionalmetalnanoparticlearraysonsurfacesbyapplying highly aligned DNA molecules or nanofibers on a surface as a template. The last chapter, Chap. 6, describes chemical preparation of metal nanoparticles and their assemblyformationprocesses.Variousmetalandsemiconductornanoparticlesare studiedaccordingtotheiruniquepropertiescontrolledbytheirsizes.Thisvolumeis publishedwiththesupportofProf.YatsuioftheUniversityofTokyo,anAssociate Editor. I hope that this volume will be a valuable resource for readers and future specialistsinnanophotonics.
