Abstract

Stimulated Brillouin scattering couples optical and acoustic waves with applications for signal processing, narrow-linewidth lasers, and environmental sensors. While traditional interactions were fixed in acoustic-wave character and frequency, more recent techniques with engineered optical waves enable new flexibility. In this talk I will discuss the development of tunable stimulated Brillouin interactions with A) low-frequency guided acoustic waves and B) surface-acoustic waves. Interactions with fundamental guided acoustic waves enable record coupling strengths and linewidths ideal for sensors and signal processing, and interactions with surface-acoustic waves enable versatile contact-free optical control and spectroscopy of state-of-the-art saw cavities for classical and quantum applications.
