| Research Abstract |
Semiconductor microtubes containing quantum wells or quantum dots in the micro-ring resonators are the candidate for developing novel high efficient and low threshold lasers. We performed the evaluation of the fabrication condition of the microtubes and numerical simulation. As a result, we found the best condition of the wet-etching, oscillating modes, the bad influence of the optical absorption in substrates on realizing lasing.
