  • Analyzed system performance considering QD device saturation effects.
  • Investigated the influence of noise levels on the stability of generated PRBS signals.

    • Main Results:

    • Demonstrated the capability of producing stable, high-speed optical PRBS signals.
    • Identified key performance-dependent parameters: relaxation lifetime, injected current density, bit repetition rate, pulse width, and pulse energy.
    • Achieved PRBS generation speeds of approximately 250 Gb/s under specific device conditions (e.g., ~1.0 ps relaxation time, >1.8 kA/cm² current density, <1.0 pJ pulse energy).

    Conclusions:

    • The proposed QD SOA-based scheme is effective for generating high-speed all-optical PRBS.
    • Optimizing QD device parameters and operational conditions is critical for achieving high-speed PRBS generation.
    • The system shows promise for applications requiring stable, high-rate optical data streams.
