我们提出了一种基于混合声子-光子波导中的前向受激布里渊散射的片上全光学模式转换方案。为了描述模式转换，同时考虑辐射压和电致伸缩力，建立了 FSBS 的理论模型。对基本模式E-11(x)到高阶模式E-21(x)的模式转换进行了数值模拟。结果表明，模式转换效率受波导长度和输入泵浦光功率的影响，考虑混合波导中光学和声学吸收损耗的影响，最高效率可达88%。此外，在1550nm通信频段可实现约12.5THz的转换带宽。这种片上模式转换器是集成光学系统中一种很有前途的器件，它可以有效地增加片上光学互连的硅数据总线的容量。 (c) 2014 年美国光学学会
We propose a scheme for on-chip all optical mode conversion based on forward stimulated Brillouin scattering in a hybrid phononic-photonic waveguide. To describe the mode conversion the theoretical model of the FSBS is established by taking into account the radiation pressure and the electrostriction force simultaneously. The numerical simulation is carried out for the mode conversion from the fundamental mode E-11(x) to the higher-order mode E-21(x). The results indicate that the mode conversion efficiency is affected by the waveguide length and the input pump light power, and the highest efficiency can reach upto 88% by considering the influence of optical and acoustic absorption losses in the hybrid waveguide. Additionally, the conversion bandwidth with approximate 12.5 THz can be achieved in 1550nm communication band. This mode converter on-chip is a promising device in the integrated optical systems, which can effectively increase the capacity of silicon data busses for on-chip optical interconnections.
