Integrated Zero Index Metamaterials

We design and fabricate an on-chip Dirac-cone metamaterial with impedance-matched zero index in optical regime. Our metamaterial consists of low-aspect-ratio silicon pillar arrays in an SU-8 matrix clad above and below by gold thin films. This design can...

Using nonlinear scattering theory, we simulate nonlinear signal generation in 2-dimensional zero-index metamaterials based on a photonic Dirac cone at the Γ point. We observe unique phase- matching in multiple simultaneous directions as the index...

Zero-refractive-index metamaterials have been proposed as potential candidates for super-coupling applications, where light is confined to sub-diffraction limited length scales on-chip. Such a device allows for efficient coupling between disparate modes...

We present an on-chip Dirac-cone metamaterial with an impedance- matched zero refractive index at lambda = 1550nm. The design is a square array of air holes in 220-nm silicon- oninsulator (SOI) which offers compatibility with complementary metal-oxide...
