Tunable Stimulated Brillouin Scattering in Planar Optical Circuits.

摘要

Stimulated Brillouin Scattering (SBS), whereby light interacts coherently with acoustic phonons is a powerful and flexible mechanism for the control of optical pulses, having recently been used to achieve tunable slow- light as well as find application in a range of important technologies such as Brillouin lasers, sensors, opto-mechanical oscillator and tailoring optical forces. Conversely SBS is undesirable in many applications, one example of which is nonlinear optics, where it leads to output power saturation and must be suppressed. The ability to control (i.e. enhance or suppress) SBS in integrated optical chips is therefore key to the realization of many applications in modern photonics that involve light-sound and light-light interactions.
