On-chip zero-index metamaterials

Journal Article

Metamaterials with a refractive index of zero exhibit physical properties such as infinite phase velocity and wavelength. However, there is no way to implement these materials on a photonic chip, restricting the investigation and application of zero-index...

Integrated impedance-matched photonic Dirac-cone metamaterials

Conference Paper

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...

Dirac-like cone-based electromagnetic zero-index metamaterials

Journal Article

Metamaterials with a Dirac-like cone dispersion at the center of the Brillouin zone behave like an isotropic and impedance-matched zero refractive index material at the Dirac-point frequency. Such metamaterials can be realized in the form of either bulk...

Integrated super-couplers based on zero-index metamaterials

Conference Paper

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...

CMOS-compatible Zero-Index Metamaterial

Conference Paper

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...

Phase-Matching in Dirac-Cone-Based Zero-Index Metamaterials

Conference Paper

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...
