Abstract
Timing restrictions for coincidence of control and data signal pulses to a soliton-based optical logic device are significantly relaxed by predistorting a characteristic of data signal pulses input to the device. Predistortion in the form of normal dispersion is sufficient to cause each predistorted data signal pulse to change shape subsequently in the optical logic device and thereby permit effective interaction between the data signal pulses and the control pulses to achieve the desired result of the logic operation. The temporal separation between control and data signal pulses has been extended to cover a total range of up to four pulse widths without degrading the operation of the optical logic device.
