Engineering solid state quantum systems is one of the grand challenges in the 21st century. In this talk I will review several approaches to controllably manipulate and engineer single emitters in wide bandgap semiconductors – promising qubits for scalable nanophotonics.
In the first part of my talk I will show self-assembly methods to couple luminescence from single quantum emitters (the nitrogen vacancy centers) to plasmonic waveguides. The technique is promising to achieve scalable quantum plasmonic circuitry components at the nanoscale.
In the second part, I will talk about our progress in studying optical properties of two dimensional (2D) systems – mainly hexagonal boron nitride monolayers. We discovered novel ultra bright, room temperature single photon emitters from these materials and thoroughly studied their optical properties. I will present detailed studies of these emitters and promising ways to engineer them in 2D layers. The field of 2D materials beyond grapheme is rapidly expanding and our results are the first evidence for quantum emission at room temperature from these systems.
I will summarize by reviewing some of the challenges and highlight promising directions in the field of quantum emitters and nanophotonics with band gap semiconductors.

Who am I?

Igor Aharonovich received his B.Sc (2005) and M.Sc (2007) in Materials Eng from the Technion Israel Institute of Technology. He then moved to Australia and pursued his PhD studies at the University of Melbourne under the supervision of Prof Steven Prawer. In 2011, Igor took a postdoctoral position at Harvard University at the group of Prof Evelyn Hu. In 2013 he became a leader of the Nanophotonics Group in UTS: School of Mathematical and Physical Science. Now he is the Associate Professor and Australian Research Council Discovery Early Career Research Fellow of School of Mathematical and Physical Sciences, University of Technology Sydney.
He is the Editorial Board Member of Nature Scientific Reports and the Executive Committee Member of the Secretary of the Australian Carbon Society. He is also the Member of the Materials Research Society (MRS) and the SPIE, and the reviewer for top tier international journals including Nature family journals, Physical Review journals, ACS Nano, Nano Letters, Advanced Materials etc. He has more than 90 peer reviewed journal publications with more than 1500 citations (Google Scholar, March 2016),including 3x Nature sister journals, PNAS, Advanced Materials, Nanoletters/ACS Nano, and Phys. Rev. Lett etc.
