Welcome to the Cotrufo Lab
Welcome to the Cotrufo Lab
We are a research group located at The Institute of Optics, University of Rochester. Our research focuses on optical metamaterials and quantum optics for a broad range of applications, including imaging, analog computation, and efficient generation and manipulation of classical and quantum light.
Research Highlights
Image processing metasurfaces containing phase change materials can be reconfigured by temperature variations smaller than 10° C, Nature Communications 15 (1), 2237, (2024).
Nonlinear metasurfaces with tailored geometrical asymmetries makes free-space light propagation nonreciprocal, Nature Photonics 18 (1), 81–90, (2024).
Experimental demonstration of optical metasurfaces performing analog temporal differentiation. By cascading two metasurfaces, more complex operations can be obtained, npj Nanophotonics 1 (39), (2024).
By simultaneously tailoring the spatial and temporal nonlocality, we demonstrated a metasurface performing mixed spatio-temporal differentiation, Phys. Rev. Lett. 133, 063801, (2024).
Metallic antennas loaded with semiconductor multi-quantum-wells act as ultra-thin power limiters and saturable absorbers, npj Nanophotonics 1 (14), (2024).
Silicon metasurfaces with engineered angle- and wavelength-dependent response can perform analog image processing, Nature Communications 14 (1), 7078, (2023).
