: 'Single-photon emission enhancement' seen as step toward quantum technologies (Purdue News)
A hyperbolic metamaterial comprised of alternating layers of titanium nitride and aluminum scandium nitride has been used by the research groups of Purdue Profs. V. Shalaev and A. Boltasseva to enhance the rate of single-photon emission by nitrogen-vacancy centers in diamond. The application areas of single-photon sources include quantum communication and quantum computing.
: Prof. A. Boltasseva and Prof. V. Shalaev elected to Purdue Innovator Hall of Fame
for developing plasmonics to advance optical technologies, improve data-storage capabilities and solar thermophotovoltaic cell performance.

: NMTI announces breakthrough solutions for HAMR nanoantenna for next-generation ultra-high density magnetic data storage.
"Researchers at Nano-Meta Technologies Inc.
(NMTI) in the Purdue Research Park have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today's computers. (Purdue News
)." This is the promise of HAMR (Heat-Assisted Magnetic Recording) technology.
The source of heat in HAMR is laser light focused by a plasmonic nano-antenna. First, we replaced "soft" noble metals as construction materials for the nano-antenna with titanium nitride (TiN) - a thermally and mechanically durable ceramic. Further, we modified optical properties of TiN, making it intrinsically less light-absorbing, and covered the TiN nano-antenna with an ultra-thin protective layer, preventing surface oxidation. HAMR is expected to enable data storage densities 10-100 times greater than those of the current magnetic storage devices.
