Electrically Driven Hyperbolic Nanophotonic Resonators as High Speed, Spectrally Selective Thermal Radiators
John Andris Roberts, Po-Hsun Ho, Shang-Jie Yu +1
We introduce and experimentally demonstrate a new class of electrically driven thermal emitter based on globally aligned carbon nanotube metamaterials patterned as nanoscale ribbon…
Multiple Tunable Hyperbolic Resonances in Broadband Infrared Carbon-Nanotube Metamaterials
John Andris Roberts, Po-Hsun Ho, Shang-Jie Yu +5
Aligned, densely-packed carbon nanotube metamaterials prepared using vacuum filtration are an emerging infrared nanophotonic material. We report multiple hyperbolic plasmon resonan…
Tunable Hyperbolic Metamaterials Based on Self-Assembled Carbon Nanotubes
John Andris Roberts, Shang-Jie Yu, Po-Hsun Ho +3
We show that packed, horizontally aligned films of single-walled carbon nanotubes are hyperbolic metamaterials with ultra-subwavelength unit cells and dynamic tunability. Using Mue…
Strong and broadly tunable plasmon resonances in thick films of aligned carbon nanotubes
Kuan-Chang Chiu, Abram L. Falk, Po-Hsun Ho +5
Low-dimensional plasmonic materials can function as high quality terahertz and infrared antennas at deep subwavelength scales. Despite these antennas' strong coupling to electromag…
