| 2 | Fiber coupled high count-rate single-photon generated from InAs quantum dots显示文摘In this work,we achieve high count-rate single-photon output in single-mode(SM)optical fiber.Epitaxial and dilute InAs/GaAs quantum dots(QDs)are embedded in a GaAs/AlGaAs distributed Bragg reflector(DBR)with a micro-pillar cavity,so as to improve their light emission extraction in the vertical direction,thereby enhancing the optical SM fiber’s collection capabil-ity(numerical aperture:0.13).By tuning the temperature precisely to make the quantum dot exciton emission resonant to the micro-pillar cavity mode(Q~1800),we achieve a fiber-output single-photon count rate as high as 4.73×10^(6) counts per second,with the second-order auto-correlation g2(0)remaining at 0.08. | Yao Chen Shulun Li Xiangjun Shang Xiangbin Su Huiming Hao Jiaxin Shen Yu Zhang Haiqiao Ni Ying Ding Zhichuan Niu | 2021 | Journal of Semiconductors2021，42，7： | 0 |
| 3 | Room-temperature optically pumped InAs/GaAs quantum dots microdisk lasers on SiO2/Si chip显示文摘We report on room temperature continuous-wave optically pumped InAs/GaAs quantum dot whispering gallery mode microdisk lasers, heterogeneously integrated on silica/silicon chips. The microdisks are fabricated by photolithography and inductively coupled plasma etching. The lasing wavelength is approximately 1200 nm and the obtained lowest laser threshold is approximately 28 μW. The experimental results show an approach of possible integrated Ⅲ–Ⅴ optical active materials on silica/silicon chip for low threshold WGM microdisk lasers. | Pengyi Yue Xiuming Dou Xiangbin Su Zhichuan Niu Baoquan Sun | 2018 | Journal of Semiconductors2018，39，8： | 0 |
| 4 | Quantum light source devices of In(Ga)As semiconductor self-assembled quantum dots显示文摘A brief introduction of semiconductor self-assembled quantum dots (QDs) applied in single-photon sources is given. Single QDs in confined quantum optical microcavity systems are reviewed along with their optical properties and coupling characteristics. Subsequently, the recent progresses in In(Ga)As QDs systems are summarized including the preparation of quantum light sources, multiple methods for embedding single QDs into different microcavities and the scalability of single-photon emitting wavelength. Particularly, several In(Ga)As QD single-photon devices are surveyed including In(Ga)As QDs coupling with nanowires, InAs QDs coupling with distributed Bragg reflection microcavity and the In(Ga)As QDs coupling with micropillar microcavities. Furthermore, applications in the field of single QDs technology are illustrated, such as the entangled photon emission by spontaneous parametric down conversion, the single-photon quantum storage, the chip preparation of single-photon sources as well as the single-photon resonance-fluorescence measurements. | Xiaowu He Yifeng Song Ying Yu Ben Ma Zesheng Chen Xiangjun Shang Haiqiao Ni Baoquan Sun Xiuming Dou Hao Chen Hongyue Hao Tongtong Qi Shushan Huang Hanqing Liu Xiangbin Su Xinliang Su Yujun Shi Zhichuan Niu | 2019 | Journal of Semiconductors2019，40，7： | 0 |
| 5 | Command filter-based I&I adaptive control for MIMO uncertain systems with input saturation and disturbances显示文摘This paper develops a control strategy based on immersion and invariance(I&I)adaptive methodology for a class of multi-input multi-output(MIMO)systems in the presence of parametric uncertainty,input saturation,and external disturbance.To avoid the analytic calculation in the backstepping process,a highgain auxiliary system is constructed to compensate for the effect of command filter error.The first-order command filters are also employed in the construction procedure of the I&I adaptive law to simplify its design and remove the structural conditions on the regressors.A filter-based disturbance observer is developed to counteract the effect of the external disturbance produced by a partially known exogenous system.To overcome the input saturation nonlinearity,a smooth function is introduced to approximate the input saturation with an extended state and a bounding estimation law.Stringent analysis guarantees the stability of closed-loop system.Finally,simulated examples confirm the effectiveness of the suggested method. | Qi Han Zhitao Liu Hongye Su Xiangbin Liu | 2023 | Science China(Information Sciences)2023，66，12： | 0 |
| 6 | The sex determination gene doublesex is required during adulthood to maintain sexual orientation显示文摘Gender differences in behavior are prevalent among animal kingdoms. The causal links among a particular gene, neural circuitry, and gendered behaviors have long been of particular interest in neuroscience. The fruit fly, Drosophila melanogaster, is a wonderful animal model with fruitful genetic tools to tackle these questions(Guo et al., 2019). It has been found that two sex determination genes,fruitless(fru) and doublesex(dsx), jointly govern the sex differences in the nervous system that regulate the male-specific courtship behavior(Burtis and Baker, 1989;Ito et al., 1996;Ryner et al. | Qionglin Peng Jiangtao Chen Xiangbin Su Rong Wang Caihong Han Yufeng Pan | 2022 | Journal of Genetics and Genomics2022，49，2： | 0 |
| 7 | Bright semiconductor single-photon sources pumped by heterogeneously integrated micropillar lasers with electrical injections显示文摘The emerging hybrid integrated quantum photonics combines the advantages of different functional components into a single chip to meet the stringent requirements for quantum information processing.Despite the tremendous progress in hybrid integrations of III-V quantum emitters with silicon-based photonic circuits and superconducting single-photon detectors,on-chip optical excitations of quantum emitters via miniaturized lasers towards single-photon sources(SPSs)with low power consumptions,small device footprints,and excellent coherence properties is highly desirable yet illusive.In this work,we present realizations of bright semiconductor SPSs heterogeneously integrated with on-chip electrically-injected microlasers.Different from previous one-by-one transfer printing technique implemented in hybrid quantum dot(QD)photonic devices,multiple deterministically coupled QD-circular Bragg Grating(CBG)SPSs were integrated with electrically-injected micropillar lasers at one time via a potentially scalable transfer printing process assisted by the wide-field photoluminescence(PL)imaging technique.Optically pumped by electrically-injected microlasers,pure single photons are generated with a high-brightness of a count rate of 3.8 M/s and an extraction efficiency of 25.44%.Such a high-brightness is due to the enhancement by the cavity mode of the CBG,which is confirmed by a Purcell factor of 2.5.Our work provides a powerful tool for advancing hybrid integrated quantum photonics in general and boosts the developments for realizing highly-compact,energy-efficient and coherent SPSs in particular. | Xueshi Li Shunfa Liu Yuming Wei Jiantao Ma Changkun Song Ying Yu Rongbin Su Wei Geng Haiqiao Ni Hanqing Liu Xiangbin Su Zhichuan Niu You-ling Chen Jin Liu | 2023 | Light(Science & Applications)2023，12，3： | 0 |
| 8 | Robust immersion and invariance adaptive coordinated control for a class of biaxial gantry systems显示文摘This paper proposes a robust Immersion and Invariance(I&I)adaptive coordinated controller for a class of uncertain linear-motor-driven biaxial gantry system subject to external disturbances for high-accuracy contour tracking.Firstly,the dynamic model of the gantry system is transformed into task coordinate frame,through which the contour tracking can be regarded as a regulation problem.Based on the transformed system dynamics,an I&I-based adaptation law with smooth projection is proposed to estimate the unknown parameters.Different from traditional adaptive control,the proposed robust I&I adaptive control introduces a new term called tuning function in adaptation law to shape the dynamic behaviour of the estimation vector.Then the stability of the closed-loop system is proved by Lyapunov theory.Finally,comparative experiments are executed on an industrial biaxial gantry system with two different cases to verify the effectiveness of the proposed control law. | Kangjun Wang Xiangbin Liu Hongye Su | 2022 | Journal of Control and Decision2022，9，3： | 0 |
| 9 | Immersion and invariance adaptive control of a class of continuous stirred tank reactors显示文摘An immersion and invariance(I&I) manifold based adaptive control algorithm is presented for a class of continuous stirred tank reactors(CSTR) to realize performance-oriented control in this paper. The nonlinear contraction method is combined into the control law design to render the closed-loop CSTR system globally asymptotically stable, firstly. Then, the I&I method is used to form the adaptation law such that the off-the-manifold coordinate(the parameter estimation error) converges to zero using P-monotone property enforced by selecting tuning function in manifold. As a result, the state of the closed-loop CSTR converges to its desired value asymptotically. The simulation is given to illustrate the effectiveness of the presented algorithm. | Gaiyan HONG Xiangbin LIU Hongye SU | 2015 | Control Theory and Technology2015，13，1： | 0 |
