Strong fiber Bragg grating based asymmetric FabryPerot sensor system with multiple reflections for high sensitivity enhancement
Optimized parameters of the sensitivity enhancement system. The system is lighted by our ultra-narrow line width erbium-doped fiber ring laser. The system has finer noise floor. The sensitivity of the system can be improved about 19 dB(nine times) in the bandwidth of 808000Hz.
