We propose an asymmetric elliptical-hole dual-core photonic crystal fiber (AE-DC-PCF) for hydrostatic pressure sensing. The transmission spectra of the AE-DC-PCF under hydrostatic pressure and the relationship between pressure sensitivity and the minor axis ratio at different elliptical ratios have been calculated. Our results show that the AE-DC-PCF has higher pressure sensitivity than that of conventional dual-core photonic crystal (DC-PCF) fiber which has the circular-hole. Based on a 10 cm fiber, the pressure sensitivity of the AE-DC-PCF as high as 50.6 pm/MPa were achieved at 1.55 μm, which is higher than the pressure sensitivity obtained from conventional DC-PCF (32.2 pm/MPa).
