Optical logical operations have sparked major interest in the past decades since it can enable many applications, particularly those involving high-throughput and on-the-fly data processing such as ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
