A new device architecture of an all-optical logic inverter (AOLI) has been proposed in this study. The AOLI functions based on stimulated Raman scattering (SRS) in silicon nanocrystal embedded slotted photonic crystal waveguide (SPCW). The operating power and footprint size of the proposed device have significantly been scaled down to ∼1.5 mW and , respectively, by combining the benefits of giant SRS gain of silicon nanocrystal and ultra-high spatio-temporal confinement of the SPCW. Cascadability of the proposed AOLI has been investigated using the maximum product criterion of the noise margin. The successful operation of the AOLI has been demonstrated for the repetition rate of the pulses as high as 100 Gbps. Finally, tolerance of performance of the design under different types of fabrication imperfections has also been calculated to establish its sustainability in a practical scenario.

用于硅光子电路大规模集成的全光逻辑逆变器

这项研究提出了一种新的全光逻辑逆变器（AOLI）的设备架构。AOLI在硅纳米晶体嵌入缝隙光子晶体波导（SPCW）中基于受激拉曼散射（SRS）起作用。拟议器件的工作功率和占位面积已显着缩小至约1.5 mW，并且 分别结合了硅纳米晶体的巨大SRS增益和SPCW的超高时空限制的优点。建议的AOLI的级联性已使用噪声余量的最大乘积准则进行了研究。已证明AOLI的成功运行具有高达100 Gbps的脉冲重复率。最后，还计算了在不同类型的制造缺陷下设计的性能公差，以在实际情况下确定其可持续性。
