Abstract:
1. A method of correcting for timing jitter of an optical data pulse in an optical transmission system, the method including: i) generating a chirped pulse containing a spread of wavelengths; ii) applying the chirped pulse to one input of an optical AND gate in synchronism with the unjittered arrival time of the data pulse; iii) applying the optical data pulse to a second input of the optical AND gate to trigger the AND gate and to produce at the output of the AND gate an output optical pulse having a wavelength determined by the amount of jitter experienced by the data pulse with respect to the unjittered arrival time; and thereafter (iv) passing the optical output pulse through a suitable optically dispersive medium so that the output pulse is correctly retimed to compensate for the jitter of the optical data pulse.
