(2) to establish the theoretical model of the active optical micro-ring resonator (MRR), clarifying the internal mechanism of ultrafast time-domain integral and dynamic storage, and realizing the active-MRR-based ultrafast all-optical integration and all-optical memory; to analyze the effects of pulse broadening and compression of all-optical integrator and all-optical differentiator, and to prove their reciprocal operation by experiment. (3) to investigate the all-optical integration, the control mechanisms, and Ziegler-Nichols parameter adjustment rules of the OPID system, to build the ultrafast control system based on OPID, analyze adjustment process by optical feedback based on the cross-modulation effect in QD-SOA, and realize ultrafast coherent control and self-locking of amplitude and polarization for femto-second optical pulses. The completion of this project will be helpful to solve the developing bottleneck of ultrafast optical control technology, while make the precise quantum manipulation and measurement possible.
