Abstract

We present a model and a rigorous method to calculate the transmission coefficient of silicon micro-rings with complex waveguide cross-section including non-linear effects and self-heating, with very short simulation times. The method is applied to the design of MRRs in the SISCAP platform with high Q and reduced non-linearity, namely due to two photon absorption and free carrier absorption. We demonstrate that the free carrier diffusion in rib waveguides and Shockely-Read-Hall recombination play a fundamental role in reducing the impact of non-linearities in the ring.

具有复杂波导截面和最小非线性的硅光子微环谐振器设计

我们提出了一个模型和严格的方法来计算具有非线性效应和自热的复杂波导截面的硅微环的透射系数，并且模拟时间很短。将该方法应用于SISCAP平台中高Q、减少非线性（即双光子吸收和自由载流子吸收）的mrr设计。我们证明了肋波导中的自由载流子扩散和肖克利-里德-霍尔复合在减少环中非线性的影响方面起着重要作用。
