1. Frequency comb Brillouin microscopy
Abstract : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. READ MORE

2. Formation and Dynamics of Molecular Excitons and their Fingerprints in Nonlinear Optical Spectroscopy
Abstract : An efficient transfer of energy in molecular systems has proven to be of fundamental importance both in nature and industrial applications. The ability of molecules to work together forming collective excitations, so-called excitons, plays a key role in for example the extraordinary fast energy transfer involved in the first steps of photosynthesis.

3. Advanced characterization techniques of photonic devices with frequency combs
Abstract : Integrated photonics has witnessed remarkable progress in the last decades. Measuring photonic devices in amplitude and phase provides insight into their performance. Swept wavelength interferometry is a prominent technique for the broadband characterization of the complex response. READ MORE

4. Characterization of domain switching and optical damage properties in ferroelectrics
Abstract : Nonlinear optical frequency conversion is one of the most important key techniques in order to obtain lasers with wavelengths targeted for specific applications. In order to realize efficient and tailored lasers, the quasi-phase-matching (QPM) approach using periodically-poled ferroelectric crystals is getting increasingly important. READ MORE

5. Dynamic and quasi-stationary electrochromic response of amorphous tungsten oxide thin films : In situ combined electrochemical and optical measurements during lithium intercalation
Abstract : Electrochromic (EC) materials can adjust their optical properties, reversibly, by means of an external electrical stimulus. They have relevant technological applications; for example, energy-efficient smart windows, which can adapt dynamically—according to the given environmental conditions—to control the heat and visible light fluxes between the interior and exterior of a building.
