Strain sensitivity enhancement based on periodic deformation in hollow core fiber

Recent progress in optical fiber Mach–Zehnder interferometers (MZIs) has gained many achievements in sensing application. However, the strain sensitivity of optical fiber MZIs is low due to the low elasto-optical coefficient of silica. In this Letter, we propose and demonstrate a method to modulate...
