Research Areas

Our research interests are related to ultrafast photophysics-photochemistry, non-linear optics, and optical fibers.

Ultrafast phenomena-photophysics

Ultrafast phenomena are the physical phenomena that occur in the femtosecond to picosecond time scale. Particularly we are interested in studying the ultrafast dynamics of phenomena such as electron or proton transfer, energy transfer, vibrational or solvent relaxation etc. We study both isotropic and anisotropic excited state dynamics. For the study of longer excited state dynamics, such as population fluorescence decay, molecular rotations in viscous environments etc. we also apply time resolved spectroscopy in the 1-400 ns timescale. We are interested in the photophysical ultrafast study of organic molecules, self-assembled systems, tri-branched molecules, nanocomposites and biomaterials. (read more)

Nonlinear Optics

We work on the study of non-linear optical phenomena (e.g two photon absorption) in new organic materials. Additionally, we are interested in the development of new techniques for studying nonlinear optical properties in order to simplify experimental efforts and mathematical calculations. Materials such as dipolar, quadrupolar and octupolar organic systems with a variety of electron donating and withdrawing groups are of our interest. In addition, we apply two-photon absorption in order to develop micro-nano-structures in three-dimensions made by photopolymerization or photobleaching. This mask-less, direct laser writing technique is based on the confinement of TPA to a very small volume (a few hundreds of femtoliters). (read more)

Optical Fibers

The development of fiber lasers as well as of fiber optical sensors based on fiber Bragg Gratings and photonic crystal fibers are our research interests on this field. (read more)
