Interactions between light and sound in the form of Brillouin scattering have been posited for a century and studied in detail since the advent of the laser. Recent developments in design and fabrication of nonlinear optical waveguides have led to the first demonstrations of Stimulated Brillouin Scattering in integrated platforms, opening up the promise of new approaches to control of RF signals in compact circuits and compact ultranarrow band lasers. I will provide a background to the field of on-chip Brillouin scattering and introduce a new Hamiltonian theory for describing the complex interactions involved in a natural way.
Brief CV of Prof.Michael Steel:
Prof Michael Steel is the Head of the Department of Physics and Astronomy within the Faculty of Science and Engineering at Macquarie University. He is also currently Interim Director of Australian Astronomical Optics – Macquarie, the newest department in the University. He is responsible for the oversight of all academic functions in both of these departments. He obtained his PhD in nonlinear optics from the University of Sydney (Australia) in 1996 and held postdoctoral positions at the University of Auckland (New Zealand) and Columbia University (New York). His research focuses on the application of integrated nonlinear photonic devices to optical signal processing and quantum information. His group’s interests include nonlinear optics in periodic structures, integrated quantum photonics, magneto-optic and non-reciprocal devices, and femtosecond laser induced waveguides in glasses.
