Our project aims to exploit a novel biomedical photonic device to be applied for biotechnologies and medicine by merging photonic technologies and LSI (large scale integration) technologies. Collaborating with photonic device, biotechnology and brain-nerve researchers, we will explore the new paradigm of the photonic LIS devices for brain sciences the clinical applications to functional brain disease such as Parkinson and epilepsy.

Emission of Continuous THz Waves by Making Use of Superconductors and Its Applications

Website of Lab

High temperature superconductors consist of thin CuO2 superconducting layers which stack in an atomic level, forming multi-Josephson junctions in a crystal. By exciting Josephson plasma in all Josephson junctions in a crystal synchronously we recently succeeded in generating intense, coherent and monochromatic continuous THz waves similar to LASER. We clarify the physical mechanism of this emission phenomenon and develop technology to generate more intense THz waves. We also employ spectroscopy of matter using this THz waves.

Functional Control of the Primary Process of Photosynthesis in Nano Space

Website of Lab

Photosynthetic pigment-protein complexes whose structures are modified are organized into lipid bilayer systems or onto electrodes in order to fabricate artificial photosynthetic membranes. These samples are subjected to the analyses using ultra-fast time-resolved coherent spectroscopy as well as time-resolved microscopic spectroscopy in order to make feasible the real time observation of excitation energy transfer. Determination of the phonon properties of these samples in broad spectral range is also performed. Based on all these investigations comprehensive understandings of the mechanisms of the excitation energy-transfer in the primary process of photosynthesis will be achieved. At the same time the way of utilization of photosynthetic systems as bio-nanodevices will be postulated. The expected outcomes are to establish guiding principles that lead the fundamental science and technology in the field of bio-nanotechnology of the 21st century.

RIKEN (The Institute of Physical and Chemical Research), Chief Scientist

High-brightness deep-ultraviolet (UV) light-emitting diodes (LEDs) or laser diodes (LDs) with emission wavelengths in the range of 230-350 nm have a wide range of potential applications, such as in water purification, sterilization, medicine and biochemistry, white light illumination, and light sources for high density optical recording. In this study, we will develop a crystal growth technique of nitride InAlGaN based semiconductors for obtaining deep-UV emitting devices, and achieve 230-250 nm band high-efficiency deep-UV LEDs and LDs.

Website of Lab

The optical technology that brings out the ultimate capabilities of ultra-short-pulse intense lasers enables us to precisely control a variety of laser-matter interactions. We are developing a few cycle laser system of ~30-TW peak power using the optical parametric amplification pumped by a laser diode-pumped solid state laser. We will release this laser to many applications adopting the spatiotemporal phase control and spatial polarization control. We aim to provide the technological base of adaptive power photonics for innovative applications of high-power lasers.
