Common-path dual-wavelength quadrature phase demodulation of EFPI sensors using a broadly tunable MG-Y laser.
TL;DR: A common-path dual-wavelength phase demodulation technique for extrinsic Fabry-Perot interferometric (EFPI) sensors is proposed on the basis of a broadly tunable modulated grating Y-branch (MG-Y) laser to address the three main concerns of existing dual-Wavelength phase interrogation methods.

Fabry-Perot interferometers built by photonic crystal fiber pressurization during fusion splicing
TL;DR: It was found that the size of thePCF voids contributes to control the cavity size independently of the pressure in the PCF, and the strain sensitivity of the interferometers is higher when the cavities are ellipsoidal than when they are spherical.
