We show how a strongly driven single-mode oscillator coupled to a first-order dynamical system gives rise to induced absorption or gain of a weak probe beam and associated fast or slow light depending on the detuning conditions. We derive the analytic solutions to the dynamic equations of motion, showing that the electromagnetically induced transparency- (EIT-) like response is a general phenomenology, potentially occurring in any nonlinear oscillator coupled to first-order dynamical systems. The resulting group delay (or advance) of the probe is fundamentally determined by the system damping rate. To illustrate the practical impact of this general theoretical framework, we quantitatively assess the observable consequences of either thermo-optic or free-carrier dispersion effects in conventional semiconductor microcavities in control/probe experiments, highlighting the generality of this physical mechanism and its potential for the realization of EIT-like phenomena in integrated and cost-effective photonic devices.

一阶动力系统的电磁感应透明度

我们展示了与一阶动力系统耦合的强驱动单模振荡器如何根据失谐条件引起弱探测光束和相关快光或慢光的诱导吸收或增益。我们推导出动态运动方程的解析解，表明类似电磁感应透明 (EIT) 的响应是一般现象学，可能发生在任何与一阶动力系统耦合的非线性振荡器中。由此产生的探头群延迟（或提前）基本上由系统阻尼率决定。为了说明这个一般理论框架的实际影响，
