Today's Colloquium:
Exploring the Quantum Universe with Light
Brian Anderson, University of Arizona College of
Optical Sciences, will present Exploring the Quantum Universe with
Light. Abstract: Did you
know that the College of Optical Sciences holds the record for the
coldest temperatures ever recorded in Arizona? Or that optics
and lasers are crucial for cooling matter to a few billionths of a
degree above absolute zero? Such ultracold gases of atoms,
called Bose-Einstein condensates (BECs), are routinely made here at
the University of Arizona. They have become one of the hottest
tools in physics research, from studies of the quantum mechanical
world of the very small and cold, to principles involving the
evolution and structure of the Universe. In this colloquium, I
will first describe how light is used to create, manipulate, and
observe these cold objects. I will point out some of the remarkable
relationships between BECs and laser light, and provide insight into
an emerging field of physics: coherent atom optics. I
will finally focus on how BECs and laser light can be used together
in studies of fundamental physics, emphasizing recent experimental
accomplishments of my research group at the College of Optical
Sciences.
Stanley Pau is the host.
Today's Colloquium begins at 3:30 p.m. in Meinel 307.
Student Photo Opportunity
Students, Rick Shoemaker is once again offering to
take or re-take student pictures -- this time on Friday morning at
9:50 a.m. in the new third floor lobby. If your smiling mug
isn't on our fourth floor photoboard or on our Web site (your family

Ultrafast Gain Dynamics, Electronic Transport,
and Pulse Propagation in Quantum Cascade Lasers
 On
Friday, September 21, Theodore B. Norris, Professor of Electrical
Engineering and Computer Science at the University of Michigan at Ann
Arbor, will present a special seminar titled Ultrafast Gain
Dynamics, Electronic Transport, and Pulse Propagation in Quantum
Cascade Lasers. Abstract:
Quantum cascade lasers are semiconductor devices used to generate
coherent mid-infrared to terahertz radiation. In a QCL, electrons
cascade through a series of quantum well active regions coupled by
superlattices. In each active region, the electron emits a photon
via an intersubband transition in the quantum wells. Thus, lasing in
a QCL results from a close interaction between the stimulated
emission process and electronic transport through the
heterostructure. We have used femtosecond mid-infrared pump-probe
techniques to observe directly this coupling of transport and
lasing. We have observed the recovery of the gain due to electronic
resonant tunneling, phonon-assisted tunneling, and superlattice
transport. We have also elucidated how the stimulated emission
process drives the transport (current) through the device - a
process we refer to as "photon-driven transport." This process
occurs even just below threshold, when there are only on the order
of 100 photons in the cavity, so this constitutes an observation of
the coupling of a quantum process to transport. Finally, we have
also investigated the propagation of ultrashort pulses in the QCL
waveguide, and have observed evidence for coherent pulse propagation
effects.
Galina Khitrova and Hyatt Gibbs are the hosts.
The seminar begins at 10:30 a.m. in Meinel 821.
