【研究成果の概要】
Structures that guide surface waves on a photonic crystal were designed by simulation. These structures made of a slab of dielectric material were patterned into microstructures to realize near-zero-index guided modes that were used to launch surface waves on the photonic crystal. The separation between adjacent near-zero-index slabs was used to control the formation of constructive and/or destructive interferences that realize different optical functions mimicking optical logic gates. AND, OR, and XOR logic gates were proposed and the XOR gate was demonstrated experimentally. The logic gate device was fabricated by patterning guiding slabs by electron beam lithography, and the device response was characterized using a microscopic setup operating in the telecommunication wavelengths.
