Self-aligned photonic defect microcavities with site-controlled quantum dots
C. -W. Shih, I. Limame, C. C. Palekar +4
Despite the superiority in quantum properties, self-assembled semiconductor quantum dots face challenges in terms of scalable device integration because of their random growth posi…
High-quality single InGaAs/GaAs quantum dot growth on a CMOS-compatible silicon substrate for quantum photonic applications
Imad Limame, Peter Ludewig, Ching-Wen Shih +4
We present the direct heteroepitaxial growth of high-quality InGaAs quantum dots on silicon, enabling scalable, cost-effective quantum photonics devices compatible with CMOS techno…
Twist Angle Dependence of Exciton Resonances in WSe/MoSe Moiré Heterostructures
Chirag Chandrakant Palekar, Joakim Hagel, Barbara Rosa +7
Van der Waals heterostructures based on TMDC semiconducting materials have emerged as promising materials due to their spin-valley properties efficiently contrived by the stacking-…
Quantum dots for photonic quantum information technology
Tobias Heindel, Je-Hyung Kim, Niels Gregersen +2
The generation, manipulation, storage, and detection of single photons play a central role in emerging photonic quantum information technology. Individual photons serve as flying q…
Applying a Riesz-projection-based contour integral eigenvalue solver to compute resonance modes of a VCSEL
Lilli Kuen, Fridtjof Betz, Felix Binkowski +6
We investigate the calculation of resonance modes of a VCSEL with a Riesz projection eigenvalue solver. The eigenvalue solver is based on the principle of contour integration where…
In-situ spontaneous emission control of MoSe-WSe interlayer excitons with near-unity quantum yield
Bo Han, Chirag Chandrakant Palekar, Sven Stephan +12
Optical resonators are a powerful platform to control the spontaneous emission dynamics of excitons in solid-state nanostructures. Here, we study a MoSe-WSe van-der-Waals h…
