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...

One-step direct-laser metal writing of sub-100 nm 3D silver nanostructures in a gelatin matrix

Journal Article

Developing an ability to fabricate high-resolution, 3D metal nanostructures in a stretchable 3D matrix is a critical step to realizing novel optoelectronic devices such as tunable bulk metaldielectric optical and THz metamaterial devices that are not...
