January 13, 2015: '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.

November 21, 2014: 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.

February 2014 - The OPTICS category in the ISI Web of Science contains over 80 journals, which in total publish between 20,000 and 30,000 papers each year. Out of about 250,000 papers published in these journals from January 2005 to January 2014, three papers from the Shalaev group are among the top 10 most cited publications and they are ranked, in terms of the number of citations, as #5 (Ref. 145 in the List of Publications; 1,025 citations), #7 (Ref. 125; 891 citations), and #8 (Ref. 153; 711 citations).
July 23, 2013 - A former PhD student in Prof. Shalaev's research group Satoshi Ishii receives 27th High Technology Award for Originality (the second place in the competition) for his work "Metallic Lenses for Diffraction Optics and Sub-Diffraction Optics". In his work at Purdue University, S. Ishii experimentally demonstrated that plasmonics and optical metamaterials can offer unique enhancements to the diffraction properties of metallic nanoslit lenses.
The developed metallic lenses included polarization-selective nanoslit lenses which work similarly to conventional convex or concave lenses, depending on (linear) polarization of the incident light; intensity-tunable nanoslit lenses with liquid crystals; and sub-wavelength focusing lenses with hyperbolic metamaterials. All these lenses are thin and planar and, thus, are suitable for the conventional planar fabrication and integration technologies. Learn more ...
