Optofluidic Photonic Crystal Fiber-Based Sensors

Over the last few years, there has been a growing interest in the field of microstructured optofluidic waveguides and especially those created by filling photonic crystal fibers with fluids. This paper presents an overview of sensing properties of optofluidic photonic crystal fiber-based sensors of temperature, pressure, electric/magnetic field, and refractive index that utilize photonic crystal fibers infiltrated with both isotropic and anisotropic liquids.
