摘要：
A selectively ethanol-filled twin-core photonic crystal fiber (TC-PCF) sensing scheme is proposed and the-oretically investigated for highly sensitive temperature sensing. Different filling cases and fiber structure were simulated to investigate the mode coupling of two solid fiber cores of the TC-PCF. Our calculation for the sensing performance shows that with properly designed fiber structure and filling configuration, a high temperature sensitivity of -16.7 nm/? could be achieved in a range from 20 to 50 ??.
