ItemMultiplexing optical fiber Fabry-Perot interferometers based on airmicrocavities(SPIE, 2019-08-28) Herrera, R. A. Pérez ; Novais, Susana ; Bravo, M ; Leandro, D ; Silva, Susana ; Frazão, Orlando ; Lopez-Amo, MIn this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors have been multiplexed in a single network and have been monitored using the commercial FBGs interrogator in combination with FFT calculations. Results show a sensitivity of 2.18 π rad/mε and a crosstalk-free operation.
