Abstract

Expressions for the center of gravity movement and dispersive spreading velocities for pulses, consisted of only one full light field oscillation at the wave guiding media input, are obtained. It is shown that for such extremely short regarding to a number of optical pulse oscillations these velocities are directly proportional to dispersive characteristics of a waveguide and inversely proportional to a square of an initial duration of the pulse.

Keywords: single-period pulses, propagation, dispersion
