“…Basically, the building blocks are confined to templates by electrostatic interaction, [356][357][358][359] hydrogen bonding, 183,360 covalent linkage, 361 encapsulation 362 or geometric confinement. [363][364][365][366][367] Thanks to the enormous availability of templates and their customizable shapes and dimensions, it is possible to control the length and sequence of 1D colloidal chains and the number and density of building blocks, and design the orientation of single particles, helical structures and the chirality. This ultimately realizes precisely regulated properties of 1D chains by tuning the type and shape of templates.…”

Far-field high-density optics storage and readout involve the interaction of a sub-100 nm beam profile laser to store and retrieve data with nanostructure media. Hence, understanding the light–matter interaction responding in the far-field in such a small scale is essential for effective optical information processing. We present a theoretical analysis and an experimental study for far-field and non-intrusive optical mapping of nanostructures. By a comprehensive analytical derivation for interaction between the modulated light and the target in a confocal laser scanning microscopy (CLSM) configuration, it is found that the CLSM probes the local density of states (LDOSs) in the far field rather than the sample geometric morphology. With a radially polarized (RP) light for illumination, the far-field mapping of LDOS at the optical resolution down to 74 nm is obtained. In addition, it is experimentally verified that the target morphology is mapped only when the far-field mapping of LDOS coincides with the geometric morphology, while light may be blocked from entering the nanostructures medium with weak or missing LDOS, hence invalidating high-density optical information storage and retrieval. In this scenario, nanosphere gaps as small as 33 nm are clearly observed. We further discuss the characterization for far-field and non-intrusive interaction with nanostructures of different geometric morphology and compare them with those obtainable with the projection of near-field LDOS and scanning electronic microscopic results.

“…[79] Recently, Meng et al developed a method to make nanoholes in polymer by using hot scanning nanoprobe, and demonstrated the assembly of single QDs and a Ag NW. [80] The assembly of QEs into the nanoholes can also be realized by chemically modifying the nanohole areas for chemical binding of QEs to the metal nanostructures. Curto et al functionalized the nanohole areas created by the second EBL step by a self-assembled monolayer of mercaptoundecanoic acid.…”

The extraordinary optical properties of surface plasmons in metal nanostructures provide the possibilities to enhance and accelerate the spontaneous emission, and manipulate the decay and emission processes of quantum emitters. The extremely small mode volume of plasmonic nanocavities also benefits the realization of plasmon-exciton strong coupling. Here, the progress on the study of plasmon modified spontaneous emission and plasmon-exciton strong coupling are reviewed. The fundamentals of surface plasmons and quantum emitters, and the methods for assembling coupling systems of plasmonic nanostructures and quantum emitters are first introduced. Then the major aspects of plasmon modified spontaneous emission, including emission intensity, lifetime, spectral profile, direction, polarization, and energy transfer are reviewed. The coupling of quantum emitters and plasmonic waveguides is then discussed. Next, the developments of strong coupling between plasmonic structures and various quantum emitters are reviewed. Finally a few applications are highlighted followed by conclusions and outlook.
