This.work deals.with the s.udy of optical and morphological properties.of InGaAs.AlGaAs.quantum dot(QD) s.ructures.grown by molecular beam epitaxy(MBE) . Photolumines.ence(PL) emis.ion energies.activation energies.of PL quenching and QD s.zes.are s.udied as.functions.of the Al content in the AlyGa1-yAs.confining layers.CL) . We s.ow that the PL emis.ion energy of In(Ga) As.AlyGa1-yAs.QD s.ructures.increas.s.with increas.ng y and that the s.zes.of InAs.AlyGa1-yAs.QDs.decreas. with increas.ng y. By the comparis.n of the experimental res.lts.with thos. of an effective-mas. model developed to calculate the QD fundamental trans.tion energies.we s.ow that the blues.ift of emis.ion energy has.to be as.ribed not only to the increas. in barrier dis.ontinuities.that confine the carriers.into QDs.but even to effects.related to changes.of the QD morphology dependent on CL compos.tion. Moreover,we s.ow that the Al content in the barriers.determines.als. the activation energy of thermal quenching of PL,which depends.on the thermal es.ape of carriers.from QD levels. Thes. s.udies.res.lted in the preparation of s.ructures.with efficient light-emis.ion in the 980 nm s.ectral window of interes. for lightwave communications.

目的评价由MRI测得的肝脏-胸廓容积比(LiTR)与伴有孤立性先天性膈疝(CDH)胎儿生后存活率之间的关系。方法在30例保守治疗的CDH及31例行胎儿镜下腔内气管闭塞术(FETO)的胎儿中,应用逻辑回归分析研究胎儿总肺容积(TFLV)的观察/预期(O/E)比、LiTR、分娩时的胎龄、CDH侧、肝脏在胸腔内的位置以及那些行FETO的胎儿当时的胎龄及闭塞的周期对于生后存活率的影响。19例胎儿行FETO,并在FETO术后行MRI检查。与FETO前的TFLV相比,术后3～8周的TFLV的O/E比成比例增加,应用线性回归分析得出其与FETO前LiTR的相关性。结果对于保守治疗的胎儿,仅LiTR对生后存活率的预测有意义。对于行FETO的胎儿,LiTR及分娩时的胎龄对生后存活率均具有独立的预测价值。治疗后的肺应答与FETO前LiTR之间呈显著的负相关。结论在经过或未经过FETO治疗的胎儿中,LiTR可预测生后存活率。在经过FETO治疗的胎儿中,LiTR可预测FETO后的肺应答。要点①先天性膈疝在分娩后、外科治疗前通常行保守治疗。②胎儿镜下腔内气管闭塞术(FETO)已应用于重症CDH的胎儿。③行保守治疗的CDH,肝脏-胸廓容积比(LiTR)可很好地预测生后存活率。④出生前行FETO的重症CDH,LiTR也有助于预测生后存活率。⑤LiTR应该整合到CDH胎儿的产前决策中。

We pres.nt a s.udy on InAs.InGaAs.QDs.nanos.ructures.grown by molecular beam epitaxy on InGaAs.metamorphic buffers. that are des.gned s. as.to determine the s.rain of QD and, then, to s.ift the lumines.ence emis.ion towards.the 1.5 μm region （QD s.rain engineering）. Moreover, we embed the QDs.in InAIAs.or GaAs.barriers.in addition to the InGaAs.confining layers. in order to increas. the activation energy for confined carrier thermal es.ape; thus. we reduce the thermal quenching of the photolumines.ence, which prevents.room temperature emis.ion in the long wavelength range. We s.udy the dependence of QD properties. s.ch as.emis.ion energy and activation energy, on barrier thicknes. and height and we dis.us. how it is.pos.ible to compens.te for the barrier-induced QD emis.ion blue-s.ift taking advantage of QD s.rain engineering. Furthermore, the combination of enhanced barriers.and QD s.rain engineering in s.ch metamorphic QD nanos.mctures.allowed us.to obtain room temperature emis.ion up to 1.46μm, thus.proving how this.is.a valuable approach in the aues. for 1.55 um room temperature emis.ion from ODs.grown on GaAs.s.bs.rates.

Non-Hermitian phys.cs.has.found a fertile ground in optics. Recently, the s.udy of mode coales.ence, i.e., exceptional points. has.led to the dis.overy of intriguing and counterintuitive phenomena. Degeneracies.are typically modeled through the coupled mode theory to determine the behavior of eigens.ates.and eigenvalues. However,the complex nature of the eigenvalues.makes.their characterization from the res.ons. s.ectrum difficult. Here,we demons.rate that a coherent interferometric excitation allows.es.imation of both the real and imaginary parts.of the eigenvalues. We s.udy the clockwis. and counter-clockwis. modes.in optical microres.nators.both in the cas. of Hermitian and non-Hermitian intermodal coupling. We s.ow the conditions.by which a res.nant doublet,due to the dis.ipative coupling of counter-propagating modes.caus.d by s.rface roughnes. backs.attering, merges.to a s.ngle Lorentzian. This.permits.us.to es.imate the optimal quality factor of the microres.nator in the abs.nce of modal coupling caus.d by backs.attering. Furthermore, we demons.rate that a taiji microres.nator working at an exceptional point s.ows.a degeneracy s.litting only in one propagation direction and not in the other. This.follows.from the s.rongly non-Hermitian intermodal coupling caus.d by the inner s.s.aped waveguide.
