We developed a self-assembly method for alignment of ZnO quantum dots (QDs) into a straight line. The polarization dependence of photoluminescence intensity revealed the signal transmission via an optical near-field along the QD chain.
Nanophotonics is defined, and a physical picture of dressed photons is presented. Room-temperature nanophotonic logic gates and related devices are demonstrated. An application for an optical router system is also reviewed.
We demonstrate system architectures for nanophotonics that enable optical near-field interactions in the nanometer-scale expolited for ultra-high density system integrations beyond the diffraction limit of light and achieving novel functionalities in information and communications applications.
We report the self-assembly of a sub-100-nm dot chain, which depends on the photon energy and has a deviation of 5 nm over 100 mum using a novel effect of near-field optical desorption.
We propose and demonstrate a memory-based computation architecture combining data summation and broadcast mechanisms using optical near-field interactions between quantum dots, which will allow high-density integration beyond the diffraction-limit of light.
Summary form only given. Recently, atom manipulation by using optical near fields has been attracting a lot of interests. Optical near field can be localized in a nanometric region, being free from the diffraction limit in contrast to propagation light. The intensity distribution of optical near field decays rapidly as an exponential-like function. Because such a spatially inhomogeneous light field...
Summary form only given. Recent experimental studies have revealed distinct characteristics of optical near fields. Highly localized optical near fields could be applied to not only a high-resolution microscope beyond the diffraction limit of light but also fabrication of nanometric devices. From this point of view, a theory, which quantitatively deals with interactions between a nanometric probe...
