ABSTRACT
We investigate the phase sensitivity of the fundamental mode of hollow-core
photonic bandgap fibers to strain and acoustic pressure. A theoretical model is
constructed to analyze the effect of axial strain and acoustic pressure on the
effective refractive index of the fundamental mode. Simulation shows that, for
the commercial HC-1550-02 fiber, the contribution of mode-index variation to the
overall phase sensitivities to axial strain and acoustic pressure are
respectively approximately -2% and approximately -17%. The calculated normalized
phase-sensitivities of the HC-1550-02 fiber to strain and acoustic pressure are
respectively 1 epsilon(-1) and -331.6 dB re microPa(-1) without considering
mode-index variation, and 0.9797 epsilon(-1) and -333.1 dB re microPa(-1) when
mode-index variation is included in the calculation. The latter matches better
with the experimentally measured results.
