Coherent light-sound interactions in waveguide structures Video: https://us02web.zoom.us/j/83703088651 Despite their different nature, optical waves and acoustic vibrations can couple efficiently through the effects of electrostriction, photo-elastic effect and radiation pressure. These phenomena enable the creation and annihilation of sound waves and have a wide range of application from passive mode-locking, narrow-linewidth lasers, agile radiofrequency filters, distributed sensing to versatile signal processing. The latter includes calculus operations, signal amplification and storage of light information. |
