Systematic design of flat band slow light in photonic crystal waveguides

Li, Juntao; White, Thomas P.; O'Faolain, Liam; Gomez-Iglesias, Alvaro; Krauss, Thomas F.


We present a systematic procedure for designing “flat bands” of photonic crystal waveguides for slow light propagation. The procedure aims to maximize the group index - bandwidth product by changing the position of the first two rows of holes of W1 line defect photonic crystal waveguides. A nearly constant group index - bandwidth product is achieved for group indices of 30-90 and as an example, we experimentally demonstrate flat band slow light with nearly constant group indices of 32.5,...[Show more]
