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.

Explore how engineered materials and 2D materials can be exploited for thermal radiation beyond the black-body limit.
We have shown that spin polarized thermal radiation is a striking feature of non-equilibrium as well as non-reciprocal systems.
High temperature materials with unique properties are a major focus of our research with multiple engineering applications.
