Miniature photonic crystal optical fiber humidity sensor based on polyvinyl alcohol

A compact photonic crystal fiber (PCF) humidity sensor based on modal interference has been proposed by the use of commercial fusion splicer to collapse the holes of PCF to form a Michelson interferometer with cladding mode excitation at the fiber tip. The sensor is then dipped coated in polyvinyl a...
