In-fiber Fabry Perot interferometer with narrow interference fringes for enhanced sensitivity in elastic wave detection

In this work, we have demonstrated using a pair of in-fiber Fabry-Perot interferometer (FPI) with matched Bragg wavelength and free spectral range (FSR) for elastic wave detection based on matched filter interrogation configuration. The cavity lengths of the FPI structures are deliberately made long...
