Nanophotonics has been extensively studied with the aim of unveiling and exploiting lightmatter interactions that occur at a scale below the diffraction limit of light, and recent progress made in experimental technologiesboth in nanomaterial fabrication and characterizationis driving further advancements in the field. From the viewpoint of information, on the other hand, novel architectures, design and analysis principles, and even novel computing paradigms should be considered so that we can fully benefit from the potential of nanophotonics. This talk will briefly review information physics aspects of nanophotonics. More specifically, we present some fundamental and emergent information properties that stem from optical excitation transfer mediated by optical near-field interactions and the hierarchical properties inherent in optical near-fields. We theoretically and experimentally investigated aspects such as unidirectional signal transfer, energy efficiency, and networking effects, as well as applications such as optical securities. A stochastic analysis of light-assisted material formation is also mentioned, where an information-based approach provides a deeper understanding of the phenomena involved, such as self-organization. Furthermore, the spatio-temporal dynamics of optical excitation transfer and its inherent stochastic attributes are utilized for solution searching, paving the way to a novel computing paradigm that exploits coherent and dissipative processes in nanophotonics.
Makoto Naruse received the B.E., M.E., and Dr. Eng. degrees in information physics and computing from the University of Tokyo, Tokyo, Japan, in 1994, 1996, and 1999, respectively. From 1999 to 2000, he was a Postdoctoral Researcher of the Japan Society for the Promotion of Science. From 2000 to 2002, he was a Research Associate at the University of Tokyo, where, since 2006, he has been a Project Associate Professor. In 2002, he joined the National Institute of Information and Communications Technology, Tokyo, where, since 2003, he has been a Senior Researcher. From 2001 to 2005, he was a Researcher of the PRESTO program of the Japan Science and Technology Agency (JST).
