Linear and nonlinear microscopy and spectroscopy

Herman Offerhaus

We explore linear and nonlinear interactions of light and matter and exploit the (phase) characteristics to extract useful information. Applications include label-free imaging of pharmaceutics and tissue, analysis of (ground) water electrolytes, detection of pathogens.  The research focused on the use of nonlinear optical interaction to detect and control small amounts of specific molecules without using fluorescent labels. This was expanded to include microscopy and integrated sensing and detection. Most recently it expanded into pharmaceutical and medical imaging.

Integrated Optical Sciences

Sonia García Blanco

In the fast emerging field of Integrated Optics, our research focusses on Active Nanophotonic Devices: development of novel on-chip active devices (lasers and amplifiers) based on heterogeneous integration of rare-earth doped gain materials on passive photonic platforms, Integrated Optical Sensors and novel devices based on the combination of plasmonics and integrated optic. 

Active phase shaping and femtosecond spectroscopy

Jennifer Herek

Active control of the amplitude and phase of femtosecond light pulses allows us to create optical melodies. Such tailored pulse shapes can be fine tuned to specific electronic and vibrational response of a molecule to control its behavior in real time. We are pursuing applications in spectroscopy, medical diagnostics or treatment and the optimization of solar cell materials.
