Two Dimensional Photonic Crystal Biosensors

摘要：

　　Based on the rigorous coupled wave theory,the narrowband reflect spectral imaging characteristics on two-dimensional photonic crystal are analyzed,and two-dimensional photonic crystal sensor probe biological structure and photonic crystal biosensor system are constructed.The simulation proved that,when the adsorption medium at the surface of two-dimensional photonic crystal are different,the white light narrowband reflection resonance mode peak wavelength would drift,and the drift quantity of the peak wavelength and the refractive index of the adsorptive medium is in a linear relationship.Colored the space imaging spectra of photonic crystal,the changes of the adsorbate refractive index in different area of the photonic crystal surface can be observed,the adsorbate concentration changes can also be got.This conclusion can be applied to biochemical substances,pharmaceutical,biological molecules and environmental pollution detection.
