Abstract
We present microphotoluminescence investigations of InAs quantum dots
(QDs) integrated into self-rolling InGaAs/GaAs strained layers. The
emission signal from the QDs is redshifted due to strain relaxation and
increased in intensity after the strained layers are released from the
substrate and rolled up into tubes. We detect waveguided light at the
tube ends, which originates from the QDs at the laser excitation spot.
The possibility of integrating quantum emitters into the tube walls
acting as waveguides represents a major step toward the realization of
flexible high quality factor optical resonators based on rolled-up
nano- and microtubes.
