我们报告的XOR和XNOR操作的实施使用的电光定向逻辑电路的基础上两个级联的硅微谐振器（MRR），这两个调制通过等离子体色散效应。在MRR周围嵌入PIN二极管以实现载流子注入调制。由制造误差引起的两个名义上相同的MRR之间的固有谐振波长失配通过热光效应由每个MRR上方的两个局部微加热器补偿。施加到MRR的两个电调制信号表示两个操作的两个操作数。同时按位XOR和XNOR操作在100 Mbit/s的演示。
We report the implementation of the XOR and XNOR operations using an electro-optic directed logic circuit based on two cascaded silicon microring resonators (MRRs), which are both modulated through the plasma dispersion effect. PIN diodes are embedded around the MRRs to achieve the carrier-injection modulation. The inherent resonance wavelength mismatch between the two nominally identical MRRs caused by fabrication errors is compensated by two local microheaters above each MRR through the thermo-optic effect. Two electrical modulating signals applied to the MRRs represent the two operands of the two operations. Simultaneous bitwise XOR and XNOR operations at 100 Mbit/s are demonstrated.
