摘要:

我们提出了一类新的光子器件的周期性应力场的基础上,使二阶非线性以及准相位匹配的硅。周期性极化硅(PePSi)为硅光子学增加了周期性极化能力,并允许将硅的优异晶体质量和先进制造能力用于基于二阶非线性效应的器件。作为PePSi技术的效用的一个例子,我们提出的模拟表明,中波红外辐射可以有效地产生通过差频产生近红外与50%的转换效率。这种技术也可以用压电材料实现,这提供了动态控制X(2)非线性的能力。

英文摘要:

We propose a new class of photonic devices based on periodic stress fields in silicon that enable second-order nonlinearity as well as quasi-phase matching. Periodically-poled silicon (PePSi) adds the periodic poling capability to silicon photonics, and allows the excellent crystal quality and advanced manufacturing capabilities of silicon to be harnessed for devices based on second-order nonlinear effects. As an example of the utility of the PePSi technology, we present simulations showing that mid-wave infrared radiation can be efficiently generated through difference frequency generation from near-infrared with a conversion efficiency of 50%. This technology can also be implemented with piezoelectric material, which offers the capability to dynamically control the X(2) nonlinearity.
