Abstract

The omnidirectional reflection bands of several typical 2-D photonic crystals are presented. Numerical results show that there are omnidirectional reflection bands in photonic crystals without bandgaps. Furthermore, photonic crystal waveguides based on omnidirectional reflection bands can be constructed by using photonic crystals without bandgaps. Like conventional photonic crystal waveguides based on bandgaps, the novel waveguides can also achieve high-efficient transmission through waveguide bends with near-zero radii of curvature. This waveguide is expected to be applied to highly dense photonic integrated circuits after further research. The aforementioned results are helpful to widen the research field of photonic crystal waveguides.
