Ultra-High resolution strain sensing by phase-sensitive interrogation of a passive fiber Bragg resonator

Gray, Malcolm; Chow, Jong; Littler, Ian C M; McClelland, David


We demonstrate and compare two similar pico-strain sensing techniques by laser frequency locking to a passive Bragg grating Fabry-Perot resonator. One technique uses auxiliary phase modulation while the other employs current modulation of the diode laser
