We report on the achievement of self-organized InAs/InP quantum dot tube nanoscale ring resonators, with a wall thickness of ~70nm and diameter of ~4-5μm, that can exhibit strong coherent emission at ~1.55μm.
We have investigated the fabrication and characterization of 3-dimensionally confined optical microcavities on Si formed by self-assembled InGaAs/GaAs quantum dot microtubes. Such microcavities on Si are free of defects and exhibit a Q-factor of 3,000.
In this paper, we have performed a detailed investigation of the cathodoluminescence characteristics of InGaAs/GaAs QD microtube ring resonators fabricated by a single-step lithography process. We have unambiguously demonstrated that self-organized QD layers embedded in rolled-up microtube structures can exhibit significantly improved luminescence efficiency, compared to the as-grown layers. In addition,...
