Abstract :
In this work, the slow light modes of the polyatomic photonic crystal (PhC) which has multiple different holes in the smallest unit cell are investigated. The slow light waveguide with nearly constant group index over large bandwidth is achieved using this new photonic crystal geometry based on square lattice. The feasibility of controlling the dispersion relation through subtle structural modification is also investigated.
