Nanophotonic Systems and Their Evolution to Related Sciences

7 Nanophotonic Systems and Their Evolution to Related Sciences 

An example of evolution to a related science is atom photonics, in which the thermal motions of neutral atoms in a vacuum are controlled using optical nearfields [71]. Theoretical studies have examined single-atom manipulation based on the dressed photon model [72], and experimental studies have involved the first successful guidance of an atom through a hollow optical fiber [73]. Recent studies have examined atom-detecting devices [74], atom deflectors [75], and an atomic funnel [76]. Atom photonics will open up a new field of science that examines the interactions between dressed photons and single atoms. 

By combining the concepts of quanmm field theory, optical science, and condensed-matter physics, the author has studied nanometric materials and optical energy transfer in nanometric space. Through these studies, a theoretical picture of dressed photons was obtained. Based on this picmre, the exchange of dressed photons was 

Fundamental concepts such as the behavior of photons in nanometric space, excitation transfer and relaxation in a nanometric space, and the primary mechanisms of the phonon-assisted process should be delved into more deeply. Such fundamental studies are expected to bring about further discoveries involving the coupling of dressed photons with various elementary excitations besides coherent phonons, leading to the discovery of novel applications. This marriage of basic studies and technological applications is expected to establish a new field of dressed photon science and technology in the near future. 

Dressed photons can be utilized to establish fundamental new technologies that can replace a wide range of conventional optical technologies. Even though users will not notice their existence, it is expected that technologies exploiting dressed photons will be widely used in everyday life in the near future. This is because dressed photons can be generated universally on the surface of illuminated nanometric materials.
