In conventional optical sensing, there is a tradeoff between the device size and sensitivity. This is because of the small interaction between light and matter. By means of a microcavity system, which can confine light in a small volume, we can accomplish small size and high sensitivity simultaneously.

Polarization information of the terahertz electromagnetic wave will be useful as a novel inspection tool of the strain distribution inside plastic materials. In this panel, we introduce a high-speed terahertz polarization measurement technique which we invented recently, and future industrial applications will be discussed.

The wavelength bands of 1530-1625 nm and 1260-1360 nm are utilized for recent optical communication systems. We can enhance the transmission capacity if we open up new wavelength band (T-band) of 1000-1260 nm. We research on photonic functional circuits with superior performances for such a wavelength band.

The molecular simulations of biomolecules are used for investigating the stability and dynamics of them. I have performed computer simulations of small proteins or peptides. Especially, I have developed simulation algorithms based on physics and chemistry. I would like to extend my research to applications.

Single molecule biosensing is an attractive technology to realize the personalized medicine. In our laboratory, we are working to develop single molecule biosensor, such as DNA and biomarker, with near field optics. Our technology is much practical way for commercial products, because we do not use any micro / nano fabrication.

Recent developments in synthetic and supramolecular techniques enable us to construct photo- and electro-functional molecular nanomaterials for solar energy conversion and electronics. So far, we have reported a variety of molecular nanomaterials. The details on the preparation, structure and application will be discussed in this presentation.

Flame synthesis has many potential advantages such as high production rates, versatile, simple industrial process, and short processing time to make oxide particles. Our group has developed this synthesis technique for various functional oxide particles, i.e. nano-phosphors, porous particles and core-shell oxide particles.

Painting and coating are universal processes in industrial production. Don’t you have any experience that you are embarrassed by the spontaneous pattern formations during painting and coating? Here, we show the technology to inhibit the pattern formations developed by the research based on the concept of “growth of fluctuation in far-from-equilibrium system”.

We present bottom-up self-assembly systems using colloid particle or micro-fabricated hydrogel materials. Those self-assembled materials are integrated with other polymers such as silicone to develop device applications including robotic actuators, sensors, optical devices and medical devices.

In the current core network, link utilization is quite low, and energy consumption is too huge. In this research, we aim to reduce power consumption without reducing user satisfaction by combining the photonic leveraging the elastic optical network technology.

We are developing FPGA-based hardware accelerators for various NOSQL storages that cover key-value store, column store, and graph database.

We introduce a gradient based 3-dimensional position detection method for optical sensors. This method can be applied for making geometrical consistency between projected visual contents and real objects in a spatial augmented reality environment.

The research goal is to build a mathematical framework for engineering problems in a wide range of fields including signal processing. We have so far built a new adaptive learning paradigm using multiple reproducing kernels for nonlinear estimation. In our approach, a proper mathematical model is designed in online fashion.
