Ultrafast detection of quantum emitters

Abstract

We discuss theoretical and experimental results on the ultrafast detection of quantum emitters. We employ nano-antennas, specifically gold nanocones, to accelerate the spontaneous emission rate of silicon-vacancy color centers in diamond by orders of magnitude to generate single photons with picoseconds timescales. Moreover, we implement an optical Kerr shutter under tight focusing to be able to detect such ultrafast single photons with time resolutions down to a few hundreds of femtoseconds.

Mario Agio studied physics at the University of Pavia and Iowa State University with Prof. Lucio Claudio Andreani and Prof. Costas M. Soukoulis, respectively. He graduated in 2003 with a thesis on the fundamentals and applications of semiconductor-based photonic crystals. In 2004 he joined the Nano-Optics Group of Prof. Vahid Sandoghdar at ETH Zurich, where his research interests have broadened to single-molecule spectroscopy, near-field optics, and quantum optics. He was awarded the Prize of the Italian Physical Society for graduate students (2002) and the Latsis Prize of ETH Zurich (2010) for his accomplishments in nano optics. In 2011 he received the Habilitation in Physical Chemistry from ETH Zurich. From 2012 to 2015 and since 2021 he has been with the National Institute of Optics (CNR-INO) and the European Laboratory for Nonlinear Spectroscopy (LENS) in Florence. Since 2015 he has been responsible for the Laboratory of Nano-Optics at the University of Siegen, Germany.
