Abstract:
1. An ultrahigh-speed adaptive and all-optical method for data packet rate multiplication compatible with multiple data rates, comprising steps of: (1) Pulse width compression on low-rate data packet; (1.1) generating an ultrashort optical pulse sample sequence: using an ultrashort-pulse laser source that can be synchronized with an external data clock to generate a periodic ultrashort optical pulse sample sequence at a repetition frequency of B (1.2) subjecting an original low-rate electronic data packet and the periodic ultrashort optical pulse sample sequence at the repetition frequency of B (2) Selecting an adaptive rate multiplication factor (2.1) calculating a rate multiplication factor RM where iε{1, 2, . . . , n}, and RM i is any value greater than 1, (2.2) determining a time amount ΔT where is the period of a compressed optical data packet, (3) Compressing the period of the original low-rate optical data packet: compressing the period of the original low-rate optical data packet by an optical data packet rate multiplication unit according to the time amount ΔT (4) Acquiring the ultrahigh-rate optical data packet of the correct frame structure: screening out the ultrahigh-rate optical data packet of the correct frame structure at an output of the optical data packet rate multiplication unit with an optical gating signal.
