General Topic: Development and application of new techniques for optical imaging and spectroscopy with nanoscale spatial resolution

Tip-enhanced near-field optical microscopy

The strongly enhanced electric field in the vicinity of a sharp metal tip is used to overcome the classical diffraction limit and allows for optical spectroscopy with nanometer-scale resolution. more...

Single-walled carbon nanotubes (SWCNT)

Carbon nanotubes are cylinders made of carbon atoms. They are typically between 0.5 and 2 nm in diameter, but several microns in length. Because of their unique mechanical and electrical properties, carbon nanotubes are considered for various technological applications, e.g. integrated circuits, nanotube actuators and optoelectronic devices. more...

Cadmium selenide nanowires (CdSe NWs)

Inorganic semiconducting nanowires are promising candidates as building blocks in nanoscale optoelectronics, photovoltaics, and sensing devices owing to their unique physical properties. We use tip-enhanced near-field optical microscopy to obtain high-resolution photoluminescence (PL) and Raman images of CdSe nanowires. more...

Time-resolved spectroscopy

Optical excitation of Single-Walled Carbon Nanotubes generates excitons whose decay dynamics can reveal a lot about the underlying physics. Time-resolved photoluminescence spectroscopy is used to observe these dynamics and investigate physical properties of individual carbon nanotubes. more...

Thin films for photovoltaic applications

Organic polymers find wide application in electronics and optoelectronics due to their flexibility, low cost and non-toxicity, and appealing optical properties. We investigate the optical properties of organic semiconductor thin films deposited on nanostructured surfaces using time-resolved two-photon photoluminescence (PL) microscopy more...

Controlling near-field optical intensities by polarization pulse shaping

Ultrafast nanooptics is an emerging field that combines the concepts and tools of ultrafast spectrocopies such as coherent control of excited states with those of near-field optics. Coherent control of optical near-fields aims at shaping the spatial, spectral and temporal light distribution at the nanoscale using the properties of the input light in the far-field. more...
