Abstract

We present a rigorous experimental study of dispersion engineered silicon slot photonic crystal waveguides based in a design that takes into account the best compromise regarding electronic beam lithography, group index, propagation length and losses. Two different interferometric approaches have been implemented to measure the photon delay on several tuned flat band structures in hollow core PhC waveguides. With the use of novel materials for sensing, amplification and nonlinear integrated applications, this platform is envisioned to be an important milestone towards various applications in silicon photonics.
