PT-Symmetric Optical Materials and Structures
AFOSR MURI FA9550-14-1-0037
The assembled MURI team consists of a core applied physics and mathematics ( Christodoulides and Kottos) and experimental characterization and fabrication groups ( Abouraddy, Vardeny and Thomas). Other activities also include assembly of new polymers and quantum dots (Tsukruk). The MURI team will work in close collaboration with other AFRL units to transition expertise and knowhow.

The effort of the MURI team will involve fundamental studies of PT-symmetric effects in optics, design and modeling of such pseudo-Hermitian photonic structures, and exploration of PT concepts in other physical settings beyond optics. Participants

In the same year, he received the Feinberg Fellowship of the Weizmann Institute of Science, Israel where he stayed for a period of two years as a postdoctoral associate. In 1999 he moved to Germany as a postdoctoral research fellow at the Max Planck Institute for Dynamics and Self-Organization in Göttingen. In 2005 he has become an Assistant Professor at Wesleyan University, USA where in 2010 he was elected Associated Professor. He is the recipient of the 2006 international Pneumatikos Award given to outstanding young scientists (below forty years old) working in the fields of Nonlinear Physics, Mathematical Physics and Nonlinear Disordered Systems. In 2013 he was awarded the Douglas J. and Midge Bowen Bennet Endowed Chair awarded from Wesleyan University for a five-year term to “a newly tenured associate professor exhibiting exceptional achievement and evidence of future promise”. Dr. Kottos has published more than 100 papers in non-linear and mathematical physics, optics, mesoscopics and computational modeling of complex systems (H-index:31). He wrote a number of reviews in graph theory and wave chaos while he disseminated his research in more than 100 presentations at international conferences and inter-university colloquia.
Zeev Valentine (Valey) Vardeny Zeev Valentine (Valey) Vardeny: Department of Physics and Astronomy, University of Utah
Professor Vardeny is an experimental physicist interested in transient and steady state optical, electronic and spintronic properties of organic semiconductors in the time domain from femtoseconds to minutes. In his laboratory Prof. Vardeny synthesizes a variety of semiconducting polymers and grows various single crystals from pi-conjugated oligomers and molecules. Using a variety of pulsed laser excitations he studies the transient response of photoexcitations in doped and undoped semiconducting polymer films, molecular organic crystals, fullerenes, single walled nanotubes and dielectric and metallic photonic crystals. The transient response also includes laser action in the form of amplified spontaneous emission, random lasers, and lasing in fabricated microcavities, including microring, microdisk, opal photonic crystals and asymmetric cavities that support chaotic ray behavior. The transient dynamic investigations are complemented using steady state optical measurements such as absorption, emission and photomodulation spectroscopies, as well as optical detected magnetic resonance, photoconductivity and Raman scattering spectroscopies. In addition, the charge and spin injection from external electrodes into organic semiconductors is also investigated using a variety of metallic, ferromagnetic, and half metallic electrodes. Also being studied are the nonlinear optical spectra of these materials using the technique of four-wave-mixing, Z-scan and two-photon-absorption. The optical studies also include a variety of organic photonic crystals made out of polymers and oligomers infiltrated into synthetic opals, as well as 2D and 3D metallic photonic crystals. On a more applicative note, solid-state devices made out of the organic semiconductors, such as field-effect-transistors, organic light emitting diodes, organic photovoltaic cells, and spin-valve devices are engineered, fabricated and tested in the laboratory.
