In a holly-core fiber, should the effective index of the fundamental mode be higher or lower than the core refractive index(n=1)?

Hi, I was wondering in hollow-core fibres should the effective index of the fundamental mode be higher or less than the core's refractive index (in this case, n = 1 because the core is filled...
