TL;DR: In this article, a method is developed to produce chemically etched optical tips for near-field and confocal microscopies with valuable properties such as large transmission and no lateral light leaks.

TL;DR: In this article, a high-resolution resonant two-color laser spectroscopy on single self-assembled InGaAs quantum dots is reported, where two laser fields at two different colors resonant with the two Zeeman split optical transitions are applied to study the properties of the spin of the resident electron in the quantum dot in both the Faraday and Voigt geometries.

TL;DR: A method for absolute distance sensing by two laser optical interferometry using a low-finesse Fabry-Pérot miniature fiber based interferometer to measure absolute distances in the sub-meter range with just few nanometer repeatability.

TL;DR: In this paper, the authors performed high-resolution resonant laser spectroscopy on a single self-assembled quantum dot (QD) at liquid He temperatures and explored the two-level nature of the QD excitonic transition through the investigation of its behavior as a function of the laser power.

TL;DR: In this article, a single self-assembled semiconductor quantum dot SAQD is shown to produce highly antibunched single photon emission with nonresonant optical excitation.
