| Research Abstract |
Nano-fabrication techniques for nano-post lasers have been established. Using the techniques, it has been experimentally confirmed that a long electron spin relaxation time in quantum wells on GaAs (110)(a prospective active layer for spin nanolasers) is preserved in nano-post structures, which indicated possibility of circularly polarized lasing in nano-post spin lasers. Furthermore, investigations on long-range surface plasmon polariton modes on metal-semiconductor structures to miniaturize spin lasers in nano scale have been conducted, which clarified a new structure to obtain efficient mode amplification.
