丹麦科技大学（Denmark Technical University）博士招生 丹麦科技大学光子工程学院 纳米光学/信号处理组招博士（2个名额）。全奖有工资（18000rmb/m），单光子光源仿真设计与方向，截止日期：15/10/2014。有意者请与Prof Niels Gregersen联系：ngre@fotonik.dtu.dk，发送CV。 英语要求如下： TOEFL或者IELTS可以二选一，分数没有要求。无需GRE! 如果你已经满足上述条件，请速和我联系。随时可以申请。如果等到明年再申请，可能已经没有位置了。 还有不清楚的也请和我联系：blxx89@126.com DTU是欧洲前五的工科院校，光学方面很强，与工业界有着紧密的联系，NKT photonics就是其孵化的子公司。DTU博士学制3年，基本不会延期。 Prof. Gregersen 人非常nice， 科研实力很强，这个项目的相关文章发被Nature Photonics 和 Chemphychem作为cover发表！ 这是一个简单的主页和研究介绍和申请链接，可以参考： http://www.loqit.fotonik.dtu.dk/ http://www.fotonik.dtu.dk/englis ... 0-a4b3-279e716dc41f The Nanophotonics Theory & Signal Processing Group at DTU Fotonik, Department of Photonics Engineering at the Technical University of Denmark is seeking 2 candidates for PhD positions in the field of design and simulations of highly efficient solid-state sources of single indistinguishable photons. The position is funded by the Sapere Aude DFF Starting Grant “Linear Optics Quantum Information Technology (LOQIT). Solid-state sources of single photons are expected to play an important role in various quantum information applications, such as secure communications, quantum computation and metrology. These applications generally require near-unity efficiency and a high single-photon purity as well as indistinguishable photon emission. Furthermore, the ideal single-photon source (SPS) should be deterministic and not involve heralding or spontaneous downwards conversion. A potential platform for such a source is a quantum emitter, e.g. an InAs quantum dot, embedded in a semiconductor material. However, in a bulk material, the symmetry of the quantum dot leads to light emission in all directions. A big challenge in realizing an efficient source is thus establishing control of the light emission. The PhD students will participate in a project team, which will design SPSs meeting all the requirements of the quantum information applications. The designs will be based on the photonic nanowire, the micropillar and the photonic crystal membrane platforms. The calculations will be performed using the modal method, representing state-of-the-art in optical simulations of single-photon sources. The fabrication and characterization of the sources will take place with external world-leading fabrication partners at CEA Grenoble, the University of Würzburg and at the Niels Bohr Institute. The team will be employing the modal method for the calculations, and the PhD students will initially work on on the construction of open geometry boundary conditions and an adaptive spatial resolution formalism for the modal method. The formalisms will then be employed in the modeling tool used by the team to analyze and propose novel SPS designs, that realize a good compromise between the simultaneous requirements of high indistinguishability, high efficiency and high purity while representing a robust and manufacturable design. The candidates are thus expected to Construct modal-method simulation techniques implementing both semi-analytical and Fourier expansion descriptions of the eigenmodes. Build open boundary formalisms converging towards the true open geometry limit for both the semi-analytical and the Fourier expansion descriptions. Build an adaptive spatial resolution formalism for improving convergence in high-index contrast geometries. Employ the modal method to analyze and propose new single-photon source designs to be fabricated by the external partners. Qualifications Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering. Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. Assessment The assessment of the applicants will be made by Associate Professor Niels Gregersen and Professor Jesper M?rk. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility.
