Abstract

A novel optical fiber sensor for simultaneous measurement of pressure and surrounding refractive index (RI) based on long period gratings (LPGs) is proposed and demonstrated. This device consists of two LPGs with different wavelengths, one of them is shielded from the environment, therefore, is insensitive with surrounding RI. Since the resonant peaks of these two LPGs change differently, the simultaneous measurement has been done. The experimental results show that the device has a good performance in measurement.
