We are running forefront of nanophotonics by developing basic theories, devices, and fabrication technologies. Based on the achievement regarding nanophotonic devices, this project aims at developing ultra-high density optical signal processing systems integrated beyond the diffraction limit of light. While targeting massive amount of information and communications demands in the future as well as emerging new functional requirements such as information security, this project conducted following three sub themes exploiting the important and unique aspects of optical near-field interactions.1. Analysis of optical signal processing systems using optical near-fields We analyzed the degree of freedom available in optical signal processing systems based on optical near-field interactions based on enabling technologies and theory of optical near-fields.2. Characterization of optical signal processing based on optical near-fields Based on the analysis obtained by the sub theme 1, we characterize basic principles of the systems such as dynamical properties by using time-resolved near-field spectroscopy. We developed basic devices based3. Hierarchical properties in signal processing based on optical near-fields We theoretically analyzed hierarchical properties in near-field systems which are then exploited in application systems including interconnections between nano-scale and macro-scale.
