  • Employing a 21-line optical frequency comb with 20 GHz line spacing for injection.
  • Analyzing the asymmetry of the injection locking range under high-power conditions.
  • Investigating the phase error between input and LO combs.

    • Main Results:

    • Adjacent spectral lines can disturb injection locking if a minimum guard band is not maintained.
    • The injection locking range becomes asymmetrical relative to the free-running frequency under high-power injection.
    • Locking behavior depends on whether the DFB laser is locked to central or edge lines of the comb.
    • Phase error analysis was performed for the generated LO comb.

    Conclusions:

    • Maintaining adequate spectral separation is critical for stable multi-wavelength injection locking of DFB lasers.
    • High-power injection leads to asymmetrical locking ranges, influenced by the position of the injected comb lines.
    • The injection-locked DFB laser can serve as a seed for LO comb generation in superchannel coherent detection systems.
