Abstract
The effect of periodic strain on the beat wavelength between the guided LP0 1 and the leaky LP 11 modes is approximated around the LP1j mode cutoff. An abrupt change of the beat wavelength as a function of optical wavelength signifies the onset of the cutoff region. An order parameter is suggested to characterize the transition of the LPjj mode from a guided to a cladding mode.
