Abstract

We propose and design a high-birefringence two-core photonic crystal fiber for simultaneous measurement of pressure and temperature. One core is centered, while the other is off-center. Both cores are made non-circular by properly modifying the sizes of some air-holes surrounding them. This introduces geometric modal birefringence to the fiber. When a broadband light launches into the centered core and transmits for a few centimeters, the output spectrum is sinusoid-like due to the intermodal coupling of the supermodes guided by the two cores. For x-polarized input light, we find it has a pressure sensitivity of -21.7 pm/MPa and a temperature sensitivity of 11.6 pm/°C; for y-polarized input light, we find it has a pressure sensitivity of 18.0 pm/MPa and a temperature sensitivity of 10.7 pm/°C. Hence, simultaneous measurement of pressure and temperature can be achieved by using a matrix method.
