Different strategies towards the deterministic coupling of a single Quantum Dot to a photonic crystal cavity mode

2011

In this work we show two different procedures of fabrication aiming towards the systematic positioning of single InAs quantum dots (QDs) coupled to a GaAs photonic crystal (PC) microcavity. The two approaches are based on the molecular beam epitaxial (MBE) growth of site-controlled QDs (SCQDs) on pre-patterned structures. The PC microcavity (PCM) is introduced previous or after the growth, on each case. We demonstrate the InAs SCQD nucleation on pre-patterned PCMs and a method to perform the QD nucleation respect to an etched ruler that is used to position the PC structure after growth. For both types of structures, we have carried out microphotoluminescence (µPL) spectroscopy experiments a…

Exciton and multiexciton optical properties of single InAs/GaAs site-controlled quantum dots

2013

We have studied the optical properties of InAs site-controlled quantum dots (SCQDs) grown on pre-patterned GaAs substrates. Since InAs nucleates preferentially on the lithography motifs, the location of the resulting QDs is determined by the pattern, which is fabricated by local oxidation nanolithography. Optical characterization has been performed on such SCQDs to study the fundamental and excited states. At the ground state different exciton complex transitions of about 500 μeV linewidth have been identified and the fine structure splitting of the neutral exciton has been determined (≈65 μeV). The observed electronic structure covers the demands of future quantum information technologies.…

Association of derived neutrophil-to-lymphocyte ratio (dNLR) with pathological complete response (pCR) after neoadjuvant chemotherapy (CT)

2019

Abstract Background dNLR is a novel biomarker associated with clinical outcome in solid tumors including early stage breast cancer (BC). Here we report the association of dNLR with pCR in triple-negative (TN) and luminal BC patients (pts) treated with neoadjuvant CT. Methods This was a retrospective analysis of two randomized studies (GEICAM/2006-03 - NCT00432172 and ETNA - NCT01822314) involving 821 pts with early stage (>2cm) or locally advanced TN or luminal BC receiving anthracycline/taxane-based CT +/- carboplatin (GEICAM/2006-03) or nab-paclitaxel/paclitaxel followed by anthracycline regimen (ETNA). dNLR was calculated as the ratio of neutrophils and the difference between total leuko…
