Abstract

We investigate the strain sensitivity of long period gratings (LPGs) fabricated in hollow-core photonic bandgap fibers (HC-PBFs). The LPGs are fabricated by periodically deforming the air-holes along the PBFs by use of a CO2laser. Resonant couplings between the LP01and LP11core modes results in two highly polarization-dependant loss dips in the transmission spectrum. The sensitivity of the resonant wavelength to strain was found to vary from -1.48 to -2.4 pm/με when the grating pitch was changed from 225 to 175 μm. Theoretical investigation suggests that the size and shape of the core can have significant influence on the strain sensitivity.
