The slight deformations observed upon transmission of a light pulse through a short length of a silica glass nanofilament offer the possibility of determining the momentum of light inside the filament. Using precise numerical calculations that take into account not only the electromagnetic momentum inside and outside the filament, but also the Lorentz force exerted by a light pulse in its entire path through the nanowaveguide, we conclude that the net effect of a short pulse exiting the nanofilament should be a pull force on the end face of the filament.
