FBG is an interferometric structure, imprinted inside the core of the optical fibre with unique spectral characteristics of reflectivity. The acoustic waves created An opto-electronic oscillator based on guided acoustic wave Brillouin scattering in a photonic crystal fiber (PCF) stimulated by a light wave in 1 μm band is proposed and demonstrated. A short length of a homemade PCF stimulated by relatively low pump power leads to strong coupling between the pump and probe waves.
