摘要

We propose a new design for slow-light photonic crystal W_(1) waveguide, which uses a combination of circular and elliptical air holes arranged in a hexagonal lattice with background material of refractive index n velence 2.84. Large value of normalized delay bandwidth product (NDBP velence 0.3708) is obtained. We have also analyzed dispersion property for the structure and achieved nearly "zero-dispersion" for a very large bandwidth. Our proposed photonic crystal waveguide has slow light applications such as reduction in length and power consumption of all-optical and electro-optic switches at optical frequency.
