Sensing characteristics of hollow-core photonic crystal fibre modal interferometers
2009
In this work, sensitivity to strain, temperature and curvature of a sensor relying on modal interferometry in hollow-core
photonic crystal fibre is studied. The sensing structure is simply a piece of hollow-core fibre connected in both ends to
standard single mode fibre. An interference pattern that is associated to the interference of the light that propagates in
the hollow core fundamental mode with light that propagates in other modes is observed. The phase of this interference
pattern changes with the measurand interaction, which is the basis for considering this structure for sensing. The phase
recovery is performed using a white light interferometric technique.
