Non-perturbative calculations of excitonic complexes in quantum dots
P. Gillies,Paul A. Dalgarno,Jamie McFarlane,Richard J. Warburton,Ian Galbraith,Khaled Karrai,Antonio Badolato,Pierre Petroff +7 more
TL;DR: Using pathintegral quantum Monte Carlo, the energy of charged excitons and biexcitons is calculated for various quantum dot quantization energies in this paper, showing good agreement with measured values in contrast with a first-order perturbation approach.
Proceedings ArticleDOI
Modal imaging of a laser Gaussian-beam reflected off a surface
TL;DR: In this article, the weak modal transformation of a polarized optical Gaussian beam reflected on a surface using an optical confocal scanning setup was mapped to a TEM01 Hermite-Gaussian spatial mode.
Proceedings ArticleDOI
Cavity nano-optomechanics: a nanomechanical system in a high finesse optical cavity
Sebastian Stapfner,Ivan Favero,David Hunger,Philipp Paulitschke,Jakob Reichel,Khaled Karrai,Eva M. Weig +6 more
TL;DR: In this paper, a sub-wavelength sized nanomechanical oscillator is coupled to a high finesse optical microcavity, where a single nanorod rod is precisely positioned into the confined mode of a miniature Fabry-Perot cavity.
Patent
Device for acquiring position with confocal fabry-perot interferometer
TL;DR: In this article, the authors provided a device and method for acquiring a position with a confocal Fabry-Perot interferometer, and the device for acquiring the position includes the confocal fabry-perot interFERometer 200.
Proceedings ArticleDOI
Toward a quantum network based on semiconductor quantum dots
O. Gazzano,A. K. Nowak,V. Giesz,Vivien Loo,C. Arnold,Simone Luca Portalupi,Justin Demory,Marcelo P. Almeida,Andrew White,C. Dal Salvio,P. F. Braun,Khaled Karrai,Isabelle Sagnes,Aristide Lemaître,Loïc Lanco,Pascale Senellart +15 more
TL;DR: Recent advances in quantum dot based quantum technology are presented: scalable fabrication of bright sources of single photons or entangled photon pairs, optical nonlinearities at the few photon scales and first implementations of quantum gates as mentioned in this paper.
