Paper Abstract

Based on combining material schemes and structure optimizing of two-dimensional triangular lattice photonic crystal, one methodology to improve slow light properties are proposed to support large NDBP at any group index in a photonic crystal line defect waveguide. Firstly, the effects of first and second row holes reflective indies n1 and n2 has been discussed, respectively. Then, one of the structural parameters, radius of holes in the first row r1, has been adjusted to extend the range of group index with large NDBP. By properly adjusting various combinations of n1 and r1, the value of NDBP higher than 0.319 can be obtained at group index from 50 to 200. The design has shown the feasibility of post-fabrication technology to generate high performance slow light at any group index.
