摘要：
A new type of microstructured fiber known as dual core photonic quasi-crystal fiber is proposed for pressure and temperature sensor based on the mode coupling of the two fiber cores. The proposed fiber is highly birefringent and hence efficiently useful for sensing application. Temperature sensitivity of about 20 pm/degrees C is observed over the range of 0 to 1000 degrees C and a pressure sensitivity of -10.5 nm/MPa is observed under a pressure of range 0 to 1000 MPa.
