Belyanin Group: Optics of Semiconductors and
Nanostructures
Research highlights Electrons in semiconductor nanostructures or in a strong
magnetic field are confined into a potential well narrower than their de
Broglie wavelength. Such a quantum-confined electron gas offers a fascinating
playground for quantum optics and condensed matter physics, in which electron
wave functions, energies, transition matrix elements, scattering rates, and
many other parameters can be designed and controlled. We study
coherent and ultrafast optical phenomena in these artificial materials. We
apply the results of our theoretical analysis and numerical modeling to
design novel optical semiconductor devices with unique functionalities such
as operation in new spectral ranges, generation of ultrafast pulses,
ultra-sensitive photon detection, or ultra-broad modulation bandwidth. Our
most recent, ongoing research projects include: ·
Magnetooptical
response of dilute magnetic semiconductors ·
Coherent terahertz
optical response of low-dimensional semiconductor plasmas ·
Superfluorescence
