Assoc. Prof. Ngoc Diep Lai
We are very happy to welcome Assoc. Prof. Ngoc Diep Lai to the third knowledge sharing seminar of the GSC Network. In this seminar, he will present his research topic on "Optimization and manipulation of single photon source for future quantum communication". In a friendly and open-minded environment, we will discuss about research, collaborative potentiality and also learn from his experiences on supervision and application. You are most welcome.
Biography: Ngoc Diep Lai obtained a Ph.D. degree in laser physics at the University of Rennes 1 (France) in 2003. He spent 4 years at the National Chung Cheng University (Taiwan), for his first Postdoctoral Research. His work focused on studies of nonlinear properties of polymer materials and nanotechnologies for fabrication of polymer-based photonic crystals. In 2007, he joined the Quantum Nanophotonics Research Group of the Quantum Photonics and Molecular Laboratory (now becomes LUMIN laboratory) of the École Normale Supérieure de Cachan (now called ENS Paris-Saclay), France. He worked towards the optimization of single photons source, coherent manipulation of single-electron spin associated to color center in diamond, and super-resolution imaging techniques. He is hired in 2009 at ENS Paris-Saclay as an Assistant Professor and he became an Associate Professor in 2013. His current research focuses on elaboration of magneto/photonic/plasmonic and quantum nanostructures by optical lithography technique and various applications. He has supervised and co-supervised 13 PhD students in the domain of the photonic crystals and nonlinear photonic crystals, optical and magnetic manipulations of single solid-state emitters, plasmonics and laser. He is co-authored 73 peer-review articles, 4 book chapters, and 21 proceedings papers. He is actually a coordinator of the Monabiphot international master program.
Optimization and manipulation of single photon source
for future quantum communication
Abstract: Quantum light source is an important element for quantum application, such as quantum computer or quantum internet. In this talk, I will show how to generate single photon source by using a single quantum emitter, such as a single quantum dot and a single defect in diamond. I will demonstrate different ways to optimize the optical properties of this quantum light source, by coupling a single emitter to a photonic structure. Finally, I will show, as examples, the use of the single photon light source for demonstration of quantum experiments and for quantum communication applications.
