As research in UQO laboratory is versatile, various
prerequisite knowledge is required. In parallel with the interdisciplinary program at Graduate School of
Cogno-Mechatronics@PNU (Global BK21+), laboratory tutorials are provided separately.
Basically, a good understanding on light-matter interaction is necessary. More
specifically, physics of nanomaterials
is investigated in terms of optical properties, where novel phenomena is
uncovered by measuring the ultrafast dynamics
associated with electrons, holes or excitons.
Furthermore, the quantum nature of optical properties is engineered with a
shaped coherent laser pulse.
Beginning with classical optics and electrodynamics, the quantum nature
of materials is revised in a frame of semi-classical description. This knowledge provides insight on
optical properties and phenomena such as quantum efficiency, optical
nonlinearities, stimulated emission, carrier transport, energy transfer, and
emission quenching. At the same time, technical expertise should be complemented
such as optical alignments of mode-locking, pulse shaping, and pulse
characterization, and automatic data acquisition and control. Numerical
simulation and theoretical modeling are also necessary for refining the
analysis. Finally, the light-matter interaction is considered in an extreme
fundamental scheme of quantum optics, where a single photon interacts with a
quantized dipole state.
