In this paper, a simulation and general analysis of nonlinear microring resonators (MRRs) as all-optical switches are discussed in a flower-like structure. These MRRs are modulated through an optical pump beam, which receives temporal shift of MRRs' resonance wavelengths. These shifts are a result of the refractive index changing due to carrier injection. A green laser is used as the optical pump to shift the resonant wavelength of each MRR. This proposed structure can operate as all-optical logic gates. Of those innovations are reconfigurable structure to achieve various gates, integrating capability, and a high extinction ratio between zero and one logical levels. This configuration would be useful to design optical integrated circuits.
本文讨论了一种呈花状结构的非线性微环谐振器（MRR）作为全光开关的模拟和综合分析。这些MRR通过光泵浦光束进行调制，该光束会使MRR的共振波长发生时间偏移。这些偏移是由于载流子注入导致折射率变化的结果。使用绿色激光作为光泵浦来改变每个MRR的共振波长。这种提出的结构可以用作全光逻辑门。其中的创新包括实现各种门的可重构结构、集成能力以及零逻辑电平与一逻辑电平之间的高消光比。这种配置对于设计光集成电路将是有用的。
