We do not have a clue as to what three primary colors are lined up by semiconductor lasers, because the green emission semiconductor laser do not be developed. This research project will prepare the ground for the realization of green emission semiconductor lasers utilizing the nitride nanocolumn, which was originally proposed by the project leader's group. As lasing properties of InGaN/GaN lasers rapidly deteriorate with lengthening the lasing wavelength from blue to green, the green emission region of laser do not be realized right now. Therefore, based on the nano-crystal effect, which is expected in the nanocolumn, that is dislocation-free character, strain alleviation and suppressed In compositional fluctuation, nano-lasers will be developed aiming green emission.

Electron Cooper pairs show enhanced oscillator strengths due to their large coherent volumes, which originate from bosonic natures. Population of holes in the valence band of a quantum dot is regulated by the Pauli's exclusion principle on fermions. This project pursues the realization of diode sources generating single entangled photon pairs on demand by the combination the different quantum particles in a quantum dot. This will open new interdisciplinary area between superconductors and photonics for the applications to quantum information processing.

In this project, we aim at developing ultimate light-emission technology based on photonic crystals, by which ultrahigh efficient light-emitting device and/or large-area coherent laser with a perfect single mode and various unique beam patterns will be developed. In addition, optical phenomena including weak and strong couplings between electron-photon systems will be investigated. These studies contribute to the future quantum optical computing and the realization of photonic chips.
This research is aiming at creation of nano-photonics devices for innovative information processing and signal transfer systems by means of controlling coupled system of electrons with optical fields in nanometer-sized space. Simulation is developed for design and analysis of optoelectronic processes in spin-chain-controlled nanophotonics device and its fabrication processes by nano-photolithography. Based on expermental research of atomic/molecular level, this project will open up new field of nano-optoelectronics.

The goal of our project is to realize, 1) generation of sub-100-attosecond X-ray pulses utilizing high-harmonic-generation signals from noble gases, 2) generation of sub-femtosecond optical pulses in the near-infrared, the visible, and the near-ultraviolet region by using higher-order Raman signals from quantum solids at room temperature or induced-phase-modulation phenomenon in inner-wall-coated hollow fibers filled with noble gases, 3) reversible and selective control of gene-expression-signature by laser-field as an application of quantum-state-control method to the optical response of DNA..We will perform these researches by making full use of the control technique of electric- field waveform of a 2.8-fs clean and single (almost mono-cycle) optical pulse in the near-infrared to the visible region, the duration of which is the shortest in the world.
