| 1 | Emission properties of nanolasers during the transition to lasing显示文摘This review addresses ongoing discussions involving nanolaser experiments,particularly those related to thresholdless lasing or few-emitter devices.A quantum-optical(quantum-mechanical active medium and radiation field)theory is used to examine the emission properties of nanolasers under different experimental configurations.The active medium is treated as inhomogeneously broadened semiconductor quantum dots embedded in a quantum well,where carriers are introduced via current injection.Comparisons are made between a conventional laser and a nanolaser with a spontaneous emission factor of unity,as well as a laser with only a few quantum dots providing the gain.It is found that the combined exploration of intensity,coherence time,photon autocorrelation function and carrier spectral hole burning can provide a unique and consistent picture of nanolasers in the new regimes of laser operation during the transition from thermal to coherent emission.Furthermore,by reducing the number of quantum dots in the optical cavity,a clear indication of non-classical photon statistics is observed before the single-quantum-dot limit is reached. | Weng W Chow Frank Jahnke Christopher Gies | 2014 | Light(Science & Applications)2014，3，1： | 5 |
| 2 | Is There a Metabolic Requirement for Photorespiratory Enzyme Activities in Heterotrophic Tissues?显示文摘Dear Editor, Photorespiration is an essential metabolic process in leaves that facilitates recovery of carbon lost by the oxygenase reaction of Rubisco and avoids the accumulation of the toxic product,2-phosphoglycolate (2PG) of this reaction (Bauwe et al.,2012).However,there is also evidence to suggest that photorespiration has a more complex role during normal growth than the mere detoxification of 2PG and the recovery of 3-phosphoglycerate (3PGA) (Bauwe et al.,2012).The current view is that photorespiration is an essential mechanism to maintain optimal photosynthesis,normal growth,and development of oxygenic photosynthetic organisms in an oxygen-containing environment (Bauwe et al.,2012). | Adriano Nunes-Nesi Alexandra Florian Andrew Howden Kathrin Jahnke Stefan Timm Hermann Bauwe Lee Sweetlove Alisdair R.

| 3 | 不同观察者间在多巴酚丁胺负荷磁共振成像时识别诱发性左心室室壁运动异常的变异性显示文摘Aims: To determine the interobserver variability for identifying inducible left ventricular(LV)wall motion abnormalities during high-dose dobutamine/atropine stress cardiovascular magnetic resonance(DSMR). Methods and results: Four readers from various institutions were supplied with the image data from 150 consecutive DSMR examinations and asked to grade wall motion and image quality throughout graded doses of dobutamine infusion administered to achieve 85%of the maximum age-predicted heart rate. Inducible ischaemia was identified if more than one segment demonstrated a new or worsening LV wall motion abnormality, and significant stenosis was defined as ≥50%luminal diameter reduction by quantitative contrast coronary angiography. Seventy-seven patients(51%) had luminal narrowings ≥50%. Diagnostic performance(sensitivity, specificity, diagnostic accuracy) of all readers was 78.2, 87.0 and 82.5%. Disagreement between two readers occurred in every seventh examination. Agreement on the presence or absence of inducible wall motion abnormalities was moderate(mean kappa value 0.59, range 0.52-0.76). Diagnostic performance and disagreement were independent of the presence of luminal narrowings ≥50%or the number of diseased coronary vessels. Image quality was regarded excellent in 89.3%of standard views. Conclusion: In the setting of multiple observers from different institutions performing a diagnostic reading of DSMR examinations carried out at a single centre, the interobserver variability was low for identifying inducible LV wall motion abnormalities indicative of coronary arterial luminal narrowings ≥50%. | Paetsch I.

| 5 | Emission from quantum-dot high-β microcavities: transition from spontaneous emission to lasing and the effects of superradiant emitter coupling显示文摘Measured and calculated results are presented for the emission properties of a new class of emitters operating in the cavity quantum electrodynamics regime.The structures are based on high-finesse GaAs/AlAs micropillar cavities,each with an active medium consisting of a layer of InGaAs quantum dots(QDs)and the distinguishing feature of having a substantial fraction of spontaneous emission channeled into one cavity mode(highβ-factor).This paper demonstrates that the usual criterion for lasing with a conventional(lowβ-factor)cavity,that is,a sharp non-linearity in the input–output curve accompanied by noticeable linewidth narrowing,has to be reinforced by the equal-time second-order photon autocorrelation function to confirm lasing.The paper also shows that the equal-time second-order photon autocorrelation function is useful for recognizing superradiance,a manifestation of the correlations possible in high-βmicrocavities operating with QDs.In terms of consolidating the collected data and identifying the physics underlying laser action,both theory and experiment suggest a sole dependence on intracavity photon number.Evidence for this assertion comes from all our measured and calculated data on emission coherence and fluctuation,for devices ranging from light-emitting diodes(LEDs)and cavity-enhanced LEDs to lasers,lying on the same two curves:one for linewidth narrowing versus intracavity photon number and the other for g(2)(0)versus intracavity photon number. | Sören Kreinberg Weng W Chow Janik Wolters Christian Schneider Christopher Gies Frank Jahnke Sven Höfling Martin Kamp Stephan Reitzenstein 无 | 2017 | Light(Science & Applications)2017，6，1： | 2 |
