Abstract

In this paper, we have demonstrated a technique in which the photonic bands of two-dimensional triangular lattice photonic crystal slab waveguides can be statically tuned by nanoscale modifications, thereby enabling unprecedented adjustment to the dispersion properties of any 2D photonic crystal. Additionally, the technique facilitates the formation of layered and composite 2D PC waveguides thus opening new fabrication routes to control dispersion, propagation and dielectric contrast
