Nanophotonics is a generic technology that can overcome the deadlock of conventional photonics, in which the size is limited by diffraction limits of light. Based on interdisciplinary studies including condensed-matter physics, optical science, and quantum field theory, nanoscale materials and optical energy transfer at nanoscale have been extensively studied. The recent development on nanoscale optics opens up new concept of nanoscale optical theory, as an example dressed photon theory, and a variety of new phenomena have been investigated. The results of the basic research have been applied to numerous applications, including nanometer-sized photonic devices, nanoscale fabrication techniques, and highly efficient energy conversion. Here, we have invited a few papers that address the above topics.
