Light and Life Laboratory (Prof. Knut
Stamnes)
The name of our laboratory is meant to reflect that we are
primarily interested in the interactions of light with living
organisms in our environment and in using light as a diagnostic and
predictive tool for studying our environment. The release of
man-made trace gases and the burning of fossil fuels pose a
potential threat to our environment in terms of ozone depletion and
increased exposure to harmful ultraviolet radiation as well as a
warmer climate. The technical innovation that will be required to
mitigate and prevent harmful effects of these environmental changes
lies at the heart of Technogenesis, and a proper understanding of
light and life interactions is a prerequisite for proper
mitigation.
Photonic Science and Technology Lab (Prof.
E.A. Whittaker)
Development and application of ultra-sensitive laser
spectroscopic techniques for the detection of atoms and molecules in
the gas phase. The techniques are based primarily on high frequency
modulation spectroscopy using tunable semiconductor
lasers. Applications include fundamental spectroscopic studies of
gases and plasmas, industrial process monitoring and detection of
environmentally important species.
Laboratory for the
Study of Electron-Driven Processes (
Dr. Vladimir Tarnovsky)
Electron collisions with atoms, molecules, and free radicals;
experimental and theoretical studies of excitation, dissociation,
and ionization processes; measurement of electron attachment and
detachment cross sections and rates; collision induces emission
spectroscopy; laser induced fluorescence experiments; collision
process in low-temperature plasma; atomic processes in atmospheric
pressure plasmas; application of collisional and spectroscopic data
to plasma diagnostic techniques; active collaborations with the
Universitat Greifswald and the Institut fur
Niedertemperaturplasmaphysik (Institute for Low-Temperature Plasma
Physics), Greifswald, Germany and the Universitat Innsbruck,
Austria.
Ultrafast Laser Spectroscopy and High-Speed Communication
Lab (Prof.
R. Martini)
Using ultrashort laser pulses (<100fs), the high-speed response
of new lasers and materials, as well as passive and active
optical systems are investigated. Based on these results we look
for new ways and possibilities to realize ultrahigh-speed
optical and infrared communication networks with Terahertz
bandwidth and above. A time-resolved Terahertz (THz)
spectroscopy setup us gives additional access to the high-speed
response by measuring the optical and electrical
properties. Beside this, multiple interesting and fascinating
application in this relatively new THz-frequency range are
investigated, taking advantage of the unique control over the
optical created THz pulses and the possibility to measure phase
and amplitude at the same time.
Quantum Electron Physics & Technology (Prof.
N.H. Horing)
Dielectric response and nonlinear quantum transport for
semiconductor microstructures. Optical properties and Quantum
well semiconductor devices for control of surface optical
waveguides. Surface collective modes and interactions.
Nanoscale Device
Laboratory (Prof.
H.L. Cui)
The Nanoscale Device Laboratory at Stevens Institute of
Technology is the head of a national multi-disciplinary team of
researchers from nine universities who are collabarating in
order to study the theory, simulation and experimental
characteristics of nano/molecular electronics. The goal is to
bridge today's world of microscale electronic devices to the
future where molecular devices will be coupled with nanoscale
semiconductor devices achieving new functionalities and
performance levels. Specifically, the objectives are to:
- Delevop the underlying theory and general simulation
approaches to treat small electronic devices of any kind.
- Develop the large-scale computing approaches necessary to
simulate nano/molecular scale devices and the distributed
infrastructure to facilitate the rapid development of new
simulation programs and their use directly by
experimentalists.
- Work closely with experimentalists to verify models and to
explore new, nanoscale semiconductor devices, molecular
devices, and hybrid nano/molecular devices.
The focus of our group here at Stevens Tech is on nanoscale
semiconductor devices, device physics, transport, modeling and
large-scale simulation.
