Slow-light and microwave signal processing in optical circuits: Harnessing on-chip stimulated Brillouin scattering

摘要

We report on-chip stimulated Brillouin scattering and its application to slow-light and microwave signal processing demonstrating unprecedented group-index ∼130 for SBS slow-light and narrowband (∼20MHz) microwave photonic filter with wide tunability (2–12GHz) and large Q-factor∼520.
