Abstract

Stimulated Brillouin Scattering (SBS) – a strong nonlinear optical effect – has recently emerged as a powerful signal processing technology with applications in defence, medicine, sensing and communications. Brillouin scattering couples efficiently between light (photons) and sound waves (acoustic phonons). This coupling only occurs over a narrow frequency range which makes Brillouin physics ideal for sensing technologies, and is emerging as a critical enhancement for microwave processing applications where it provides the high-resolution, bandwidth flexibility, and reconfigurability which are major bottlenecks of state-of-the-art systems. SBS is only now starting to be harnessed in centimetre-scale integrated devices with impressive demonstrations based on silicon and chalcogenide integration, enabling unprecedented efficiency and promising significant reductions in SWaP. This talk reviews recent progress and achievements as well as challenges and opportunities.
