Non-local optical response of a multi-phased quantum material
Ding Zhang, Gururaj V. Naik
Light-matter interaction in quantum materials presents a new paradigm as light can tip the balance between many competing quantum many-body phases to result in new phenomena. Descr…
Sensing beyond the exceptional point for high detectivity
Zhichao Li, Ciril S. Prasad, Xielin Wang +2
Exceptional point (EP)-based optical sensors exhibit exceptional sensitivity but poor detectivity due to their acute sensitivity to perturbations such as noise. When the optical bu…
Large optical tunability from charge density waves in 1T-TaS under incoherent illumination
Weijian Li, Gururaj V. Naik
Strongly correlated materials possess a complex energy landscape and host many interesting physical phenomena, including charge density waves (CDWs). CDWs have been observed and ex…
Macroscopically Aligned Carbon Nanotubes as a Refractory Platform for Hyperbolic Thermal Emitters
Weilu Gao, Chloe F. Doiron, Xinwei Li +2
Refractory nanophotonics, or nanophotonics at high temperatures, can revolutionize many applications, including data storage and waste heat recovery. In particular, nanophotonic de…
Photon Upconversion with Hot Carriers in Plasmonic Systems
Gururaj V. Naik, Jennifer A. Dionne
We propose a novel scheme of photon upconversion based on harnessing the energy of plasmonic hot carriers. Low-energy photons excite hot electrons and hot holes in a plasmonic nano…
Ultra-compact modulators based on novel CMOS-compatible plasmonic materials
Viktoriia E. Babicheva, Nathaniel Kinsey, Gururaj V. Naik +3
We propose several planar layouts of ultra-compact plasmonic waveguide modulators that utilize alternative CMOS-compatible materials. The modulation is efficiently achieved by tuni…
Plasmonic resonances in nanostructured transparent conducting oxide films
Jongbum Kim, Gururaj V. Naik, Naresh K. Emani +1
Transparent conducting oxides (TCO) are emerging as possible alternative constituent materials to replace noble metals such as silver and gold for low-loss plasmonic and metamateri…
Negative refraction in Al:ZnO/ZnO metamaterial in the near-infrared
Gururaj V. Naik, Jingjing Liu, Alexander V. Kildishev +2
Noble metals such as gold and silver are the primary metallic building blocks of metamaterial devices. Making subwavelength-sized structural elements from these metals seriously li…
A comparative study of semiconductor-based plasmonic metamaterials
Gururaj V. Naik, Alexandra Boltasseva
Recent metamaterial (MM) research faces several problems when using metal-based plasmonic components as building blocks for MMs. The use of conventional metals for MMs is limited b…
Semiconductors for Plasmonics and Metamaterials
Gururaj V. Naik, Alexandra Boltasseva
Plasmonics has conventionally been in the realm of metal-optics. However, conventional metals as plasmonic elements in the near-infrared (NIR) and visible spectral ranges suffer fr…
Oxides and nitrides as alternative plasmonic materials in the optical range
Gururaj V. Naik, Jongbum Kim, Alexandra Boltasseva
As alternatives to conventional metals, new plasmonic materials offer many advantages in the rapidly growing fields of plasmonics and metamaterials. These advantages include low in…
Titanium nitride as a plasmonic material for visible wavelengths
Gururaj V. Naik, Jeremy L. Schroeder, Timothy D. Sands +1
The search for alternative plasmonic materials with improved optical properties over the traditional materials like silver and gold could ultimately lead to the long-awaited, real-…
Engineering the Photonic Density of States with metamaterials
Z. Jacob*, J. Y. Kim*, G. V. Naik +2
The photonic density of states (PDOS), like its' electronic coun- terpart, is one of the key physical quantities governing a variety of phenom- ena and hence PDOS manipulation is t…
Searching for Better Plasmonic Materials
Paul West, Satoshi Ishii, Gururaj Naik +3
Plasmonics is a research area merging the fields of optics and nanoelectronics by confining light with relatively large free-space wavelength to the nanometer scale - thereby enabl…
