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.

Novel Design

A novel design of photonic crystal waveguide crossing with taper structure is proposed. Simulations are performed by finite-difference time-domain method. The results show the proposed design has both high transmission and low cross talk characteristics. The transmission band and low cross talk band can be tuned to match each other by adjusting the taper structure..
