Pico-strain multiplexed fiber optic sensor array operating down to infra-sonic frequencies

Littler, I C M; Gray, Malcolm B; Chow, Jong; Shaddock, Daniel; McClelland, David


An integrated sensor system is presented which displays passive long range operation to 100 km at pico-strain (pε) sensitivity to low frequencies (4 Hz) in wavelength division multiplexed operation with negligible cross-talk (better than −75 dB). This has been achieved by prestabilizing and multiplexing all interrogation lasers for the sensor array to a single optical frequency reference. This single frequency reference allows each laser to be locked to an arbitrary wavelength and...[Show more]
