Spectral broadening of optical transitions at tunneling resonances in InAs/GaAs coupled quantum dot pairs
P. Kumar, C. Jennings, M. Scheibner +3
We report on linewidth analysis of optical transitions in InAs/GaAs coupled quantum dots as a function of bias voltage, temperature, and tunnel coupling strength. A significant lin…

Geometry-induced circulation of local photonic transport in a triangular metastructure
Palak Dugar, Michael Scheibner, Chih-Chun Chien
A geometry-based mechanism for inducing circulation of photons is illustrated by a metastructure consisting of quantum dots arranged in a triangle coupled to photonic structures. T…
