Dual-Core Photonic Crystal Fiber Based Temperature and Pressure Sensor for Oceanic Applications

摘要

In this paper, a micro-structured optical fiber with dual core, photonic crystal fiber (PCF), was proposed. It had specific optical properties to obtain high birefringence, small beat length, flattened dispersion for different values of structural parameters over a wide range of wavelength.Moreover, its feasibility for applications such as temperature and pressure sensors was also analyzed. The sensitivity of the temperature sensor was calculated as 20 pm/°C for 6 cm fiber, and the sensitivity of the pressure sensor was calculated as –10.5 nm/KPa.
