摘要:

利用受激布里渊散射已经证明了光学和微波信号处理的一系列独特能力。在可大规模制造的集成电路中利用布里渊散射的期望导致了对硅基材料平台的关注。硅基布里渊波导已经取得了显著的进展,但结果受到电信波长处存在的非线性损耗的阻碍。在这里,我们报告了一种新的方法来超越这个问题,通过集成的高布里渊增益材料,As2S3,到硅芯片上。我们制作了一个紧凑的螺旋设备,在硅电路,实现了一个数量级的改善布里渊放大。为了建立这种方法的灵活性,我们制造了一个环形谐振器,其自由光谱范围与布里渊频移精确匹配,从而首次在硅集成电路中演示布里渊激光。将有源光子器件与此处所示的SBS器件相结合,将能够创建具有增强功能的紧凑、可大规模制造的光路。

英文摘要:

A range of unique capabilities in optical and microwave signal processing have been demonstrated using stimulated Brillouin scattering. The desire to harness Brillouin scattering in mass manufacturable integrated circuits has led to a focus on silicon-based material platforms. Remarkable progress in silicon-based Brillouin waveguides has been made, but results have been hindered by nonlinear losses present at telecommunications wavelengths. Here, we report a new approach to surpass this issue through the integration of a high Brillouin gain material, As2S3, onto a silicon chip. We fabricated a compact spiral device, within a silicon circuit, achieving an order of magnitude improvement in Brillouin amplification. To establish the flexibility of this approach, we fabricated a ring resonator with free spectral range precisely matched to the Brillouin shift, enabling the first demonstration of Brillouin lasing in a silicon integrated circuit. Combining active photonic components with the SBS devices shown here will enable the creation of compact, mass manufacturable optical circuits with enhanced functionality.
