The field of nanophotonics aims at controlling light-matter interaction in engineered nano-scale structures such as waveguides and cavities. This area presents opportunities for rich fundamental understanding on various interaction mechanisms as well as opportunities for developing practical devices for applications such as optical communications and sensing. One of the most important mechanisms is the interaction between light and acoustic fields, referred to as Optomechanics or Brillouin interaction. On one hand, an optical pulse can excite acoustic vibrations on the waveguides and cavities while the acoustic field itself alters the propagation of light, thus creating a feedback mechanism that can be used to develop devices. The objective of this research is to design integrated fiber components for all optical signal processing based on very long tapered optical fibers (microwires) that offer unique and unmatched features to enhance light sound interaction and reinforce the collaboration between UNICAMP and FEMTO-ST in the area of photon/phonon interaction.
