In this paper, we present an all-optical XOR gate based on two-dimensional photonic crystals (PCs). The proposed gate is designed to be used in optical computing and all-optical logic applications, ...
The first commercial transistors had a top-down structure made entirely of silicon: specifically, a polysilicon gate electrode, a thin (~20 nm) SiO 2 dielectric and a silicon bulk channel 1,2. In the ...
