Two Dimensional Photonic Crystal

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.

In this paper, the channel drop filter based on two dimensional photonic crystal is proposed. The structure is made of silicon rods with the refractive index n1 = 3.4641 which are perforated in air with refractive index n2 = 1. The simulation results are obtained using 2D finite difference time domain (FDTD) method. The photonic band gap is calculated by plane wave expansion solver method. Resonant mode of the ring resonator and the filter transmission spectrum is calculated using 2D FDTD method. Full width half maximum (FWHM) bandwidth of the filter at the output transmission spectrum from 1.508 μm to 1.512 μm is 4 nm. The quality factor of the filter is 377.5 and the proposed filter design is around 21 × 15 μm which is suitable for photonic integrated circuits.

Two Dimensional Photonic Crystal

This paper analyzes the modality of two-dimensional photonic crystal micro-resonators by adopting equivalent refractive index mode. In this paper, it controls the optical field distribution only through altering the thickness of light guide layer, while the parameter like resonator structure and crystal lattice arrangement remain stable. It discusses that it would arrive at a satisfactory photon locality while the refractive index of light guide layer material is gallium nitride , the thickness of light guide layer is and its equivalent refractive index is 2.1.This reveals the influence of micro-resonator light guide layer’s thickness towards the modality, providing a preferable pre-estimate method for the actual research of micro-resonators with higher quality.
