We report the demonstration of an OR/NOR directed logic device, which consists of two cascaded micro-ring resonators (MRRs) modulated through electric-field-induced carrier depletion in reverse-biased PN junctions embedded in the ring waveguides. The resonance wavelength mismatch between the two nominally identical MRRs, caused by fabrication error, is compensated by thermal tuning. Two high-speed electrical signals applied to the PN junctions act as the operands, and the logical operation results are represented by the optical powers detected at the two output ports of the device. The working parameters of the device, including the working wavelength, the voltage applied to the micro-heater, and the voltages applied to the two PN junctions are extracted from the static response spectra of the device. Dynamic experimental results show that the OR/NOR logical operations can be achieved at the speed of 10 GHz.
我们报道了一种或/或非定向逻辑器件的演示，该器件由两个级联的微环谐振器（MRR）组成，通过嵌入环形波导中的反向偏置PN结中的电场诱导载流子耗尽进行调制。由制造误差引起的两个名义上相同的MRR之间的共振波长失配通过热调谐来补偿。施加到PN结的两个高速电信号用作操作数，逻辑运算结果由在器件的两个输出端口检测到的光功率表示。从器件的静态响应光谱中提取器件的工作参数，包括工作波长、施加到微加热器的电压以及施加到两个PN结的电压。动态实验结果表明，或/或非逻辑运算可以在10 GHz的速度下实现。
