TL;DR: In this article, the reflected image of a diffraction limited focused spot is investigated using confocal solid immersion microscopy and it is shown that the spot's image shows aberrations when reflected off objects with optical indexes lower than that of the solid immersion lens (SIL) material.

TL;DR: In one case, the spin resonance behaves as a driven 3-level lambda system with weak damping; in another one, the dot exhibits remarkably strong and narrow spin resonances with fluctuating resonant positions, evidence of unusual dynamic processes.

TL;DR: In this article, the magneto-optical properties of excitons confined in ring-shaped self-assembled semiconductor quantum dots were measured at 4.2 K as a function of the applied magnetic field.

TL;DR: The reflection of a strongly focused beam from an interface between two dielectric media, where the beam is incident from the optically denser medium, and the image generated by the reflected light is strongly aberrated.

TL;DR: In this article, the authors performed transmission spectroscopy on single quantum dots and examined the effects of a resident carrier's spin, the incident laser spot size, polarization, and power on the experimental contrast.
