We experimentally demonstrate a reconfigurable electro-optic directed logic circuit which can perform any combinatorial logic operation using cascaded carrier-injection micro-ring resonators (MRRs), and the logic circuit is fabricated on the silicon-on-insulator (SOI) substrate with the standard commercial Complementary Metal-Oxide-Semiconductor (CMOS) fabrication process. PIN diodes embedded around MRRs are employed to achieve the carrier injection modulation. The operands are represented by electrical signals, which are applied to the corresponding MRRs to control their switching states. The operation result is directed to the output port in the form of light. For proof of principle, several logic operations of three-operand with the operation speed of 100 Mbps are demonstrated successfully.
我们实验演示了一种可重构电光定向逻辑电路，该电路使用级联载流子注入微环谐振器 (MRR) 可实现任何组合逻辑操作，并且该逻辑电路是在具有标准商用互补金属氧化物半导体 (CMOS) 制造工艺的绝缘体上硅 (SOI) 衬底上制造的。嵌入在 MRR 周围的 PIN 二极管用于实现载流子注入调制。操作数由电信号表示，施加到相应的 MRR 以控制它们的开关状态。操作结果以光的形式定向到输出端口。作为原理验证，成功演示了具有 100Mbps 操作速度的三操作数的几个逻辑操作。
