本文研究了光注入半导体激光器的非线性动力学特性。测量的光谱的关键特性再现在计算的基础上，包括自发辐射噪声的单模模型。激光器在注入水平的有界范围内表现出混沌。当从较低和较高的注入水平接近混沌状态时，遵循周期加倍的混沌路线，尽管该路线被自发发射噪声所掩盖。一个新的，有界制度的周期加倍发生注入水平远高于混沌动力学区域。光注入强烈地修改了载波场共振耦合频率。
We characterize the nonlinear dynamics of a semiconductor laser subject to optical injection. The key characteristics of measured optical spectra are reproduced in calculations based on a single-mode model that includes spontaneous-emission noise. The laser exhibits chaos over a bounded range of injection levels. As the chaotic regime is approached from both lower and higher injection levels, a period-doubling route to chaos is followed, although the route is obscured by spontaneous-emission noise. A new, bounded regime of period-doubling occurs for injection levels well above the region of chaotic dynamics. Optical injection strongly modifies the carrier-field resonance coupling frequency.
