- Activities:
This group aims at exploiting the interaction of light with matter to elucidate new strategies for the manipulation, control, shaping, and processing of light beams and signals. Our current main activities are focused in nonlinear optical processes, where “light acts on itself” inside suitable materials. This includes applications to all-optical photonic devices, imaging, and quantum optics.
