Abstract

This study explores the nonlinear dynamics of semiconductor lasers under optical injection from diverse frequency comb profiles, including Gaussian, Lorentzian, graded, quadratic, and zigzag distributions. Using numerical simulations of injection-locking maps, bifurcation diagrams, and carrier dynamics, we analyze the stability and chaos within these systems. Results show that Gaussian and Lorentzian combs produce smooth and predictable locking regions, with heightened instability near chaotic thresholds. Graded combs ensure stable performance across varying injection conditions, whereas quadratic and zigzag combs exhibit fragmented yet stable locking boundaries. These findings provide insights for optimizing optical systems leveraging frequency combs for telecommunications and metrology..
