An important recent development in linear wave physics is the discovery         by M.V. Berry of Bristol Univesity, England, of an unexpected phase             shift in the adiabatic limit for the Schroedinger equation.  This phase         is acquired upon adiabatic transport of a quantum system around a               closed circuit in the parameter space of the Hamiltonian, and is solely         a topological property of the circuit.  These ideas have recently been          extended by Professor Chiao to the field of optics.  An experiment in           linear optics has shown that this phase appears as the angle of optical         rotation of linear polarization of light in a helically wound optical           fiber.  The current research extends these investigations both                  theoretically and experimentally to nonlinear wave propagation, with            emphasis on the propagation of linearly polarized optical solitons              generated by picosecond pulses inside a helical fiber.  The question of         how Berry's phase extends to the nonlinear case will thereby be partly          answered.  Potential applications of this new fundamental phenomenon            will be explored.
