摘要：

Engineering solid state quantum systems is amongst grand challenges in realizing integrated quantum photonic circuitry. While several 3D systems (such as diamond, silicon carbide, zinc oxide) have been thoroughly studied, solid state emitters in two dimensional (2D) materials are still in their infancy.

      In this talk I will introduce hexagonal boron nitride (hBN) as a promising layered material that hosts ultra bright quantum emitters. I will present several avenues to engineer these emitters in large exfoliated sheets, multilayers and 2D monolayers using top down and bottom up approaches. I will also discuss potential atomistic structures of the defects supported by density functional theory.

      I will then highlight promising avenues to integrate the emitters with plasmonic and photonic cavities to achieve improved collection efficiency and Purcell enhancement. These are fundamental experiments to realize integrated quantum photonics with 2D materials. I will summarize by outlining challenges and promising directions in the field of quantum emitters and nanophotonics with 2D materials and other wide band gap materials.

  简介：

    Professor Igor Aharonovich received his PhD in 2010 from the University of Melbourne and spent two years in Harvard as a postdoctoral researcher in the group of Prof Evelyn Hu. In 2013 Igor returned to Australia and joined the University of Technology Sydney (UTS). Igor is an associated director of the Institute of Biomedical Materials and Devices and leader of the Nanophotonics laboratory.

      Igor’s group is focusing on exploring single emitters in wide band gap semiconductors, such as diamond or gallium nitride and in emerging 2D systems such as hexagonal boron nitride. His group is also interested in innovative approaches for nanofabrication of nanophotonics devices for low threshold lasing and an on-chip integrated quantum nanophotonics.

      Igor is a recipient of the IEEE Young Investigator Award (2016, honors an individual who has made outstanding technical contributions to photonics prior to 35th birthday), The 2017 IUPAP Young Scientist Award (Commission on Laser Physics and Photonics) and the 2017 Pawsey medal from the Australian Academy of Science.
