Our
research focuses on ultrafast spectroscopy and nonlinear
optics of molecularly-engineered organic and inorganic
materials. Specific materials under current investigation
are semiconductor nanocrystals (quantum dots), polymers,
fullerenes, organometallic compounds (phthalocyanines and
porphyrins), and ordered/disordered structures made of
these materials. We study fundamental electronic energy
structures, the nature of primary photo-excitations, the
effects of many-particle interactions, carrier energy
relaxation and ultrafast recombination dynamics, and
mechanisms for optical nonlinearities, light emission and
optical gain. In additional to these fundamental research
topics, we devote much of our efforts toward developing
novel materials for device applications. This includes
our work on optical amplification, ultrafast holography,
and optical limiting. We have a complementary
experimental facility comprising broadband femtosecond
and nanosecond laser sources and instrumentation. Since
much of the work outlined above involves femtosecond
measurements, we have concentrated significant effort on
improving existing and developing new femtosecond
instrumentation and techniques. |
