我们提出并实验演示了一种基于三个级联光机械微环谐振器(mrr)的高非互易传输率(NTR)硅光二极管。由于半波导是自由悬挂的,非线性效应(包括热光效应和光机械效应)都得到了增强。在输入功率较低的情况下,光机械磁阻器的传输特性由于其强烈的非线性效应可以被灵活地控制。更重要的是,由于级联磁阻器的优化设计,ntr得到了改善。在实验中,以较低的输入功率成功地获得了较高的NTR。所提出的光二极管为片上非互反传输提供了一种互补金属氧化物半导体(CMOS)兼容解决方案,具有高NTRs、低功耗和小尺寸的优势,在片上光学计算和逻辑门中具有许多重要的应用。
We propose and experimentally demonstrate a silicon optical diode with high nonreciprocal transmission ratio (NTR) based on three cascaded opto-mechanical microring resonators (MRRs). As half waveguides of the opto-mechanical MRRs are free-hanging, the nonlinear effects (including the thermo-optic effect and opto-mechanical effect) are both enhanced. With low input powers, the transmission characteristics of the opto-mechanical MRRs could be flexibly manipulated by the strong nonlinear effects. More importantly, due to the optimized design of the cascaded MRRs, the NTRs are improved. In the experiment, a high NTR is successfully obtained with a low input power. The proposed optical diode provides a complementary metal-oxide semiconductor (CMOS) compatible solution for on-chip nonreciprocal transmission with dominant advantages of high NTRs, low-power consumption and compact size, which has many significant applications in on-chip optical computing and logic gates.
