项目摘要

The object of this group is to explore, both experimentally and theorctically, the mutual quantum manipulation effects in many-body electron systems. Especially, we have extensively studied the excitonic processes in microcavity structures.Miyano has discussed the radiative processes of dye aggregate systems regarding the localization of excitons due to the potential fluctuations and enhanced radiative interaction.Hanamura has studied the quantum mechanical manipulation of radiation field utilizing exciton-microcavity coupled system. A new scheme for squeezed light generation by one and two-photon is proposed.Gonokami has studied the nonlinear optical processes of exciton-microcavity coupled system. In the weak-coupling regime, strong enhancement of phase conjugation signal due to the internal field enhancement was observed. In the strong-coupling regime, polarization dependent degenerate four-wave mixing processes were observed and explained by a newly proposed scheme of weakly interaction boson model.Gonokami has also examined the optical processes in dielectric micro spheres in order to explore the feasibility of three dimensional confinement of optical wave. A very high value for spontaneous emission coupling rate of the order of 30% has been obtained from the threshold characteristics of lasing from dye doped polymer spheres with diameter of few micrometers. The obtained value and the experimental features have been reproduced by the wave optics calculation with vector spherical harmonic functions.Shimada has developed a new technique to make optical wavelength scale micro structures of organic systems based on the selective epitaxial growth on patterned substrate.Akiyama has developed a new optical micro probe technique of solid immersion lens with a spatial resolution of 100 nm. With this method, optical processes in semiconductor microstructures have been studied.

该组的目的是在实验和理论上探索多体电子系统中的相互量子操纵效应。尤其是，我们已经广泛研究了微腔结构中的激子过程。Miyano讨论了由于潜在的波动和增强的辐射相互作用而导致的抗激元的辐射过程。 - 微腔耦合系统。提出了一个新的针对光发射的新方案，并提出了两光子。Gonokami研究了激子微腔偶联系统的非线性光学过程。在弱偶联方案中，观察到由于内部场增强而引起的相结合信号的强大增强。在强耦合方案中，观察到了依赖性脱位的四波混合过程，并通过新提出的弱相互作用玻色子模型的新方案进行了解释。Gonokami还研究了介电微球中的光学过程，以探索三维的可行性光波的限制。从染料掺杂聚合物球的激光特征中获得了30％阶的自发发射耦合率的非常高的值，直径很少。获得的值和实验特征已经通过矢量球形谐波功能的波光学计算复制了。Shimada开发了一种新技术，以基于在模式的底物上的选择性外观上的生长。固体浸入式镜头的新型光学微探针技术，空间分辨率为100 nm。通过这种方法，已经研究了半导体微观结构中的光学过程。
