Hydrostatic Pressure Response of Mo Coated Etched Fiber Bragg Grating Sensor in Side-Hole Packaging

Abstract

We demonstrate side-hole packaged; nanolayer Molybdenum (Mo) coated etched Fiber Bragg Grating (eFBG) as hydrostatic pressure sensor. Pressure sensitivity enhancement of nearly 2000 times is observed with such a simple, ruggedized and packaged sensor system.
