我们模拟了具有双光子吸收的环形腔中的光学参量振荡,聚焦在1.55<inline-formula><tex-math notation="LaTeX">μ</tex-math></inline-formula> m的硅上。振荡是可能的,如果自由载流子吸收可以减轻;这可以通过在反向偏置的p-i-n结中使用载流子清除来减少载流子寿命来实现。通过改变泵浦功率、失谐量和反向偏置电压,可以在包括1.55<inline-formula><tex-math notation="LaTeX">μ</tex-math></inline-formula> m的宽波长范围内产生具有正常色散和异常色散的腔中的频率梳。此外,当载流子寿命足够长时,自由载流子自脉冲不稳定性导致丰富的动力学。
We model optical parametric oscillation in ring cavities with two-photon absorption, focusing on silicon at 1.55 <inline-formula><tex-math notation="LaTeX">$mu$</tex-math></inline-formula>m. Oscillation is possible if free-carrier absorption can be mitigated; this can be achieved using carrier sweep-out in a reverse-biased p-i-n junction to reduce the carrier lifetime. By varying the pump power, detuning, and reverse-bias voltage, it is possible to generate frequency combs in cavities with both normal and anomalous dispersion at a wide range of wavelengths including 1.55 <inline-formula><tex-math notation="LaTeX">$mu$</tex-math></inline-formula>m. Furthermore, a free-carrier self-pulsing instability leads to rich dynamics when the carrier lifetime is sufficiently long.
