摘要: Infiltrated liquid sensors based on a 2D photonic crystal waveguide were devised. This is designed by taking into account lowering of the radius central air holes in single row and optical resonance shifts due to refractive index change these selectively filling with different liquids. The transmission spectrum infiltrated sensor was obtained use finite difference time domain method. At working wavelength 1550 nm, mode gap edge sensitivity 200 nm per unit. are consistent dispersion diagrams.
