Investigation on Wideband Slow Light Based on Photonic-Crystal Coupled Waveguides

Zhang Wei Wang Zhiyong Wang Wenchao Yang Hui Qiu Qi(School of Optoelectronic Information,University of Electronic Science and Technology of China, Chengdu,Sichuan 610054,China)  
A photonic-crystal coupled waveguide is proposed by introducing two line-defects to perfect triangular lattice.By analyzing the dependence of band shape on various structure parameteral,unique band with approximate zero group velocity can be obtained in an optimized photonic-crystal coupled waveguide.Moreover,by chirping the widths of the photonic-crystal waveguides in the optimized structure,a perfect wideband slow light is obtained,it possesses the bandwidth of 13.24 nm and the average group index of 28,which is verified by means of two-dimensional finite-difference time-domain(FDTD) simulations,and our numerical analysis shows that Gaussian pulses passing through the coupled waveguide have a relative temporal spreading below 10%.
