Outline of Final Research Achievements

This research project explored the possibility in the strong coupling of excitons in semiconductor particles with random cavities. For this purpose, we investigated a high quality random laser system, i.e., the random laser consisting of ZnO microparticles with the exhibition of a small number of lasing peaks with their stable lasing intensities accompanying extremely low spontaneous-emission background. We found that this better lasing characteristics is due to intra-particle confinement of random lasing modes inside a single ZnO microparticle. We also found that such a unique random lasing characteristics strongly depend on the size of the particles. However, to couple the excitons in microparticles with the random cavity modes, the present random laser needs to have lower lasing thresholds. We concluded that the size and crystalline quality of the ZnO particles should be optimized further.

Academic Significance and Societal Importance of the Research Achievements

ランダムレーザーでは、形成する共振器のQ値は低く、散乱損失が大きいため、レーザー発振しきい値は高い。本研究は酸化亜鉛のマイクロ粒子を用いランダム構造のサイズを制御することで誘起される共振器モード数を制限し、レーザー発振しきい値の低減とともに、共鳴エネルギーを狭帯域化させるという発想で、共振器-励起子を強結合させ、ランダム共振器-励起子ポラリトンレーザーという全く新しいタイプのレーザー光源を目指す点で学術的に意義深い。
