Thesis title: Controlling, storing and manipulating light using on-chip Brillouin scattering

Supervisors: Birgit STILLER , Benjamin EGGLETON

Thesis abstract:

The aim of my PhD project is to study the interaction between photons and acoustic phonons in chip-scale nonlinear waveguides. The effect I am particularly interested in is known as stimulated Brillouin scattering (SBS), where photons resonantly excite and scatter from acoustic phonons. These scattered photons are downshifted in frequency by the frequency of the acoustic phonon. By cascading this process I was able to generate an on-chip Brillouin frequency comb. In the current project I am aiming to harness SBS to demonstrate a phononic buffer by transferring data from the optical to the acoustic mode and subsequently retrieving it.
