Outline of Final Research Achievements

Spin-controlled lasers, which can emit circularly polarized coherent light, have become a focus of interest. Semiconductor quantum wells (QWs) are crucial building blocks of the spin-lasers. The main purpose of our research project is to improve characteristics of the QWs in order to realize high performance spin-lasers. In this study, we successfully demonstrated great improvement of optical and spin properties in the QWs by using (110)-oriented GaAs substrate through systematic crystal growth experiment. Our findings suggest that the newly developed (110) QWs indeed have greater advantages than the conventional (100)QWs for use in spin-lasers.
