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.

通过仿真设计了光子晶体表面波的导波结构。这些由介质材料板制成的结构被图案化成微结构，以实现用于在光子晶体上发射表面波的近零折射率引导模式。相邻近零折射率板之间的分离被用来控制建设性和/或破坏性干涉的形成，从而实现模拟光学逻辑门的不同光学功能。提出了与、或、异或逻辑门，并对异或逻辑门进行了实验验证。利用电子束光刻技术对导板进行图案化，制备了逻辑门器件，并利用电信波长下的显微装置对器件的响应进行了表征。
