Light confining devices using all-dielectric metamaterial cladding


An all-dielectric metamaterial cladding is provided that can strongly confine light inside conventional low-index dielectric waveguides for use with photonic integrated circuits and nano-photonic devices. A class of metamaterials with dual electric and magnetic anisotropy along with giant birefringence can provide the ideal quasi-transverse electromagnetic mode propagation inside a glass core. A Transformed Cladding Waveguide can show an order of magnitude decreased cross-talk as compared to conventional waveguides.
