Terahertz Characteristics of Two Dimensional Photonic Crystal Cavity Based on 3D Finite-Difference Time-Domain Method

Article Preview

Abstract:

We proposed a photonic crystal(PC) cavity of hexagonal lattice with six air holes of which the radius are different from other cylinders. In the center of this structure, the cavity can be obtained and light confinement is achieved. The Figure of E vs time apparently demonstrates that the light confinement can be observed in ultrafast time. All the Figures in this paper, calculated by 3D finite-difference time-domain method, illuminate that the structure proposed is significant in the field of PC.
