Fabrication of straight waveguide in two-dimensional photonic crystal slab and its light propagation characteristics
二维平板光子晶体直波导的制备和光传输特性的测量

Using focused ion beam lithograph, we fabricated W3 straight waveguide in two-dimensional photonic crystal slab on SOI (silicon on insulator) wafer. The light propagation was observed on top and from the end of the sample. The transmission dip and mode distribution at the outlet of ridged waveguide were measured. The results show that light can propagate in the photonic crystal waveguide.
