We use the dynamical behavior of a nonlinear fiber ring resonator and the switching capability of a nonlinear fiber coupler to produce a sequence of pulses, with polarization states changing pseudorandomly between two values, to be used as a key in quantum cryptography. The experimental setup is proposed, and simulations are performed. ©2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 79–81, 2000.
