Optoacoustic mode-locking based on micro-core photonic crystal fibre

Abstract

We review the principles and the implementation of optoacoustic mode-locking based on stimulated Raman-like scattering in PCF. Optically-driven acoustic vibrations in the few-µm-sized PCF-core creates a self-sustained temporal optomechanical lattice in a mode-locked laser cavity, enabling self-stabilized high-harmonic mode-locking as well as various highly-ordered compound pulse-patterns.
