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.

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.
