Helicity Enhanced Torsion Sensor Based on Liquid Filled Twisted Photonic Crystal Fibers
A highly sensitive torsion sensor can be constructed by combining a twisted photonic crystal fiber with a liquid-filled waveguide in its air-hole cladding. The torsion sensitivity of this type of sensor is determined directly by the phase-matching conditions between the fiber core mode and the liqui...
