Inter-dot coupling and excitation transfer mechanisms of telecommunication band InAs quantum dots at elevated temperatures
C. Hermannstädter, N. A. Jahan, J. -H. Huh +4
We investigate the photoluminescence temperature dependence of individual InAs/InGaAlAs quantum dots emitting in the optical telecommunication bands. The high-density dots are grow…
Telecommunication band InAs quantum dots and dashes embedded in different barrier materials
Nahid A Jahan, Claus Hermannstädter, Jae-Hoon Huh +8
We investigate the long wavelength (1.2 to 1.55 micro-m) photoluminescence of high-density InAs quantum dots and dashes, which were grown on InP substrates. We analyze the temperat…
Influence of the charge carrier tunneling processes on the recombination dynamics in single lateral quantum dot molecules
C. Hermannstädter, G. J. Beirne, M. Witzany +7
We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunnelin…
Polarization fine-structure and enhanced single-photon emission of self-assembled lateral InGaAs quantum dot molecules embedded in a planar micro-cavity
C. Hermannstädter, M. Witzany, G. J. Beirne +8
Single lateral InGaAs quantum dot molecules have been embedded in a planar micro-cavity in order to increase the luminescence extraction efficiency. Using a combination of metal-or…
