AI 中文摘要
我们数值研究了电泵浦垂直腔面发射激光器与悬浮反射镜的两个机械模式耦合时的频率梳产生。位移相关的腔损耗和辐射压反馈将机械运动与载流子密度和光子密度耦合，在光子密度谱中产生谐波和组合频率分量。机械品质因数主要控制梳状线的强度，而共振频率决定其频谱分布。初始机械振幅影响阈值电流和相对光谱强度，两个模式的同时激发产生更广泛的可观测分量集合。这些结果确立了在主动光机械腔中计算得到的梳状结构对机械耗散、共振频率和初始条件的依赖性。
英文摘要
We numerically investigate frequency-comb generation in an electrically pumped vertical-cavity surface-emitting laser coupled to two mechanical modes of a suspended mirror. Displacement-dependent cavity loss and radiation-pressure feedback couple the mechanical motion to the carrier and photon densities, producing harmonics and combination-frequency components in the photon-density spectrum. Mechanical quality factors primarily control the intensity of comb lines, whereas resonance frequencies determine their spectral distribution. The initial mechanical amplitudes influence the threshold current and relative spectral intensities, with the simultaneous excitation of both modes yielding a broader set of observable components. These results establish the dependence of the calculated comb structure on mechanical dissipation, resonance frequencies, and initial conditions in an active optomechanical cavity.
