edit

V. Shalaev earned a Master of Science Degree in physics (summa com laude) in 1979 from Krasnoyarsk State University (Russia) and a PhD Degree in physics and mathematics in 1983 from the same university. Over the course of his career, Shalaev received a number of awards for his research in the fields of nanophotonics and metamaterials, and he is a Fellow of several of Professional Societies (see the Awards, honors, memberships section below). Prof. Shalaev has co-/written three- and co-/edited four books, and authored over 800 research publications, in total.[15] As of May 2024, his h-index is 125 with the total number of citations nearing 70,000, according to Google Scholar.[16] In 2017-2023 Prof. Shalaev has been on the list of Highly Cited Researchers from the Web of Science Group;[17] he is ranked #9 in the optics category of the Stanford list of top 2% World's highest-cited scientists[18] (career-long; out of 64,044 entries); ranked #34 in the US and #58 worldwide in the field of Electronics and Electrical Engineering by Research.com.[19]

Research

edit

Vladimir M. Shalaev is recognized for his pioneering studies on linear and nonlinear optics of random nanophotonic composites that had helped to mold the research area of composite optical media.[2] He also contributed to the emergence of a new field of engineered, artificial materials - optical metamaterials.[1][2] Currently, he studies new phenomena resulting from merging metamaterials and plasmonics with quantum nanophotonics.[20]

Optical metamaterials

edit

Optical metamaterials (MMs) are rationally designed composite nanostructured materials that exhibit unique electromagnetic properties drastically different from the properties of their constituent material components. Metamaterials offer remarkable tailorability of their electromagnetic response via shape, size, composition and morphology of their nanoscale building blocks sometimes called 'meta-atoms'.[21] Shalaev proposed and demonstrated the first optical MM that exhibits negative index of refraction and the nanostructures that show artificial magnetism across the entire visible spectrum.[22][23][24][25] (Here and thereafter, only selected, representative papers by Shalaev are cited; for complete list of Shalaev's publications visit his website.[26]) He made important contributions to active, nonlinear and tunable metamaterials, which enable new ways of controlling light and accessing new regimes of enhanced light-matter interactions.[27][28][29][30] Shalaev also experimentally realized negative-refractive-index MMs where optical gain medium is used to compensate for light absorption (optical loss).[29] He made significant contributions to the so-called Transformation Optics,[31] specifically on optical concentrators and "invisibility cloaks".[32][33][34][35] In collaboration with Noginov, Shalaev demonstrated the smallest, 40-nm, nanolaser operating in the visible spectral range.[36][37] Shalaev also made seminal contributions to two dimensional, flat metamaterials – metasurfaces[38] – that introduce abrupt changes to the phase of light at a single interface via coupling to nanoscale optical antennas.[39][40][41][42][43] He realized extremely compact flat lens,[41] ultra-thin hologram[42] and record-small circular dichroism spectrometer[43] compatible with planar optical circuitry. MM designs developed by Shalaev are now broadly employed for research in sub-wavelength optical imaging, nanoscale lasers, and novel sensors.[38][44]

Shalaev’s work had a strong impact on the whole field of metamaterials.[1][2][3] Three of Shalaev’s papers - Refs. [22], [23], and [32] - remain among the top 50 most-cited out of over 750,000 papers included in the ISI Web of Science OPTICS category since 2005 (as of January 2021).[45]

Random composites

edit

Shalaev made pioneering contributions to the area of random optical media, including fractal and percolation composites.[2][46][47][48][49][50][51][52][53][54][55][56] He predicted the highly localized optical modes -'hot spots' - for fractals and percolating films which were later experimentally demonstrated by Shalaev in collaboration with the Moskovits and Boccara groups.[52][53] Furthermore, he showed that the hot spots in fractal and percolation random composites are related to localization of surface plasmons.[46]−[56] These localized surface plasmon modes in random systems are sometimes referred to as  Shalaev's "hot spots": see e.g.[57] This research on random composites stemmed from the early studies on fractals performed by Shalaev in collaboration with M. I. Stockman;[58][59][60][61][62][63] a theory of random metal-dielectric films was worked out in collaboration with A. K. Sarychev.[47][49][50][54] Shalaev also developed fundamental theories of surface-enhanced Raman scattering (SERS) and strongly-enhanced optical nonlinearities in fractals and percolation systems and led experimental studies aimed to verify the developed theories.[46]−[56][60][64][65] Shalaev also predicted that nonlinear phenomena in random systems can be enhanced not only because of the high local fields in hot spots but also due to the rapid, nanoscale spatial variation of these fields in the vicinity of hot spots, which serves as a source of additional momentum and thus enables indirect electronic transitions.[65]

Shalaev’s contributions to the optics and plasmonics of random media[46]−[56] helped to transform those concepts into the area of optical metamaterials.[22]−[25][27]−[36] Owing to the theory and experimental approaches developed in the area of random composites, optical metamaterials have quickly become a mature research field surprisingly rich in new physics.[24][4] Shalaev’s impact on the development of both fields is in identifying the strong synergy and close connection between these two frontier fields of optics that unlock an entirely new set of physical properties.[4]

New Materials for Nanophotonics and Plasmonics

edit

Random composites and metamaterials provide a unique opportunity to tailor their optical properties via shape, size and composition of their nanoscale building blocks, which often require metals to confine light down to the nanometer scale via the excitation of surface plasmons.[46][30] To enable practical applications of plasmonics, Shalaev in collaboration with A. Boltasseva[66] developed novel plasmonic materials, namely transition metal nitrides and transparent conducting oxides (TCOs), paving the way to durable, low-loss, and CMOS-compatible plasmonic and nanophotonic devices.[67][68][69][70][71][72][73] The proposed plasmonic ceramics operating at high temperatures, can offer solutions to highly efficient energy conversion, photocatalysis and data storage technologies[69]−.[73] In collaboration with the Faccio group,[74] Shalaev demonstrated ultrafast, strongly-enhanced nonlinear responses in TCOs that possess an extremely low (close to zero) linear refractive index – the so-called epsilon-near-zero regime.[75][76][77][78][79] Independently, the Boyd group obtained equally remarkable results in a TCO material,[80] demonstrating that low-index TCOs hold a promise for novel nonlinear optics.

Early research

edit

Shalaev’s PhD work (supervised by Prof. A.K. Popov) and early research involved theoretical analysis of resonant interaction of laser radiation with gaseous media, in particular i) Doppler-free multi-photon processes in strong optical fields and their applications in nonlinear optics[81] spectroscopy[82] and laser physics[83] as well as ii) the (newly-discovered then) phenomenon of light-induced drift of gases.[84][85]
