Frequency-stabilized limit-cycle dynamics of an optically injected semiconductor laser

摘要

Limit-cycle dynamics are self-sustained oscillations that arise in man-made nonlinear systems and in nature. In an optically injected semiconductor laser, limit-cycle oscillations can reach a frequency ten times the relaxation resonance frequency of the solitary semiconductor laser. To stabilize such oscillations, complicated circuitry is often used. Here, we demonstrate limit-cycle oscillations of inherently stable frequencies. By properly choosing the operating conditions, three distinct types of stable-frequency oscillation points are defined.
