Waveguiding in double trench photonic crystals and effects of cladding asymmetry

We investigate a novel double trench waveguide where a conventional single-mode strip waveguide is embedded into a two-dimensional photonic crystal slab. Low-loss guiding (50 dB/cm) is demonstrated with an expanded bandwidth compared to standard photonic crystal waveguides. Effects of cladding asymm...
