1. "Fat" Nanobeam-Waveguide Resonator for Suppressing Spectral Diffusion in InGaAs Quantum Dots
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : The coherent coupling of photons to solid state emitters is one of the building blocks for future quantum technology. However, one of the main sources for non-perfect or even strongly reduced coherence of the photons is charge noise which introduces energy shifts during or in between the photon emission events.

2. Realization of quantum dots emitting at 1.55µm for single photon emitters
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : This thesis reports is about the fabrication and characterization of InAs self-assembled quantum dots (QDs) using both InP and GaAs substrates for the realization of telecommunication-wavelength single-photon sources for quantum communication. The QDs were grown by metal organic vapour phase epitaxy (MOVPE) using the strain-driven Stranski-Krastanov formation mechanism. READ MORE

3. Magneto-optical studies of optical spin injection in InAs quantum dot structures
University essay from Funktionella elektroniska material; Tekniska högskolanAbstract : Optical spin injection in InAs/GaAs quantum dots (QDs) structures under cryogenic temperature has been investigated in this work using continuous-wave optical orientation spectroscopy. Circularly polarized luminescence from trions in the QDs was used as a measure for the degree of spin polarization of the carriers in the QD ground states. READ MORE
