報告題目: Highly efficient quantum light sources based on quantum dots in photonic nanostructures

報告摘要: 

     Solid-state quantum emitters, especially epitaxial quantum dots (QDs) with large optical oscillator strength, are a promising candidate for future on-chip quantum devices. However, the deterministic creation and eventual scalability of single QD devices greatly suffer from the random nature of the QD positions produced in their self-assembled growth. In this talk, I will present a new high-performance system for nanoscale location of QDs based on photoluminescence imaging. By further utilizing such a system, we’ve achieved deterministic couplings between single QDs and a variety of photonic nanostructures, which enables the realizations of quantum photonic devices with state-of-the-art performances, including ultra-bright single-photon/entangled pair sources and hybrid quantum photonic circuits.

報告人簡介: 

     Jin Liu is a professor of physics in Sun Yat-Sen University. He obtained his PhD degree in 2012 from Technical University of Denmark under the supervision of Prof. Peter Lodahl and Prof. Jesper Mork. Before moving back to China, he worked with Dr. Kartik Srinivasan at National Institute of Standards and Technology (NIST) to develop integrated quantum photonic circuits. His current research activities cover integrated quantum photonics and nanophotonics by utilizing molecular beam epitaxy, semiconductor nanofabrication and cryogenic optical characterizations.
