Direct airborne acoustic wave modulation of Fabry–Perot fiber laser (FPFL) over 100 kHz of operating bandwidth
The idea of applying a simple Fabry-Perot fiber laser (FPFL) set-up in a free-running condition as an acoustic sensing medium is proposed. Conventional optical microphone requires a stringently aligned diaphragm to mediate the acoustic impedance mismatch between air and silica fiber. Motivated by th...
