Multi-mode optical fiber taper for generating brillouin responses from forward inter-modal interactions with fundamental acoustic modes, methods and systems thereof

Abstract

A method of generating a Brillouin signal resonance response by forward inter-modal Brillouin scattering with fundamental acoustic modes (FIM-FAM), by generating an optical mode in an optical fiber, wherein the optical mode is a fundamental optical mode; generating another optical mode in another optical fiber, wherein this optical mode is a higher-order optical mode; coupling through a mode selective coupler the pair of optical modes to become coupled optical modes; controlling and transmitting the coupled optical modes within an input multi-mode optical fiber; driving a fundamental acoustic mode in a multi-mode optical fiber taper, wherein at least one Brillouin signal resonance response is generated within the multi-mode optical fiber taper.
