Prof. Pertsch’s research targets the control of light at the nanoscale and at the quantum level using nanostructured materials and ultrafast nonlinear optical effects. Research interests include:
Ultrafast light-matter interactions and optical quantum phenomena in nanostructured matter, as e.g. photonic nanomaterials, metamaterials, photonic crystals, and 2D semiconductors (TMDCs)
Nonlinear spatio-temporal dynamics, plasmonics, near field optics, high-Q nonlinear optical microresonators, opto-optical processes in integrated optics, and alloptical signal processing
Integrated quantum optics, quantum imaging, and quantum sensing
Multi-tip scanning nearfield optical microscopy (SNOM) and photoemission electron microscopy (PEEM)
Application of photonic nanostructures for multifunctional diffractive optical elements, for efficiency enhancement of photovoltaic elements, and for astronomical instruments
