High-Resolution Cathodoluminescence (CL) for Characterization of Nanophotonic Structures

David Gachet

Attolight AG

David Gachet got a PhD in physics from the University of Aix-Marseille, France (2007) working on novel non-invasive contrasts in optical microscopy. He was a postdoctoral researcher for 2.5 years (2008-2010) at Weizmann Institute of Science (Israel) and Fresnel Institute (Marseille, France) working on optical spectroscopy and microscopy of nanoparticles. In 2010, he was appointed Assistant professor at the University of Aix-Marseille (France). In 2013, he joined the Swiss company Attolight as the head of the Analytical laboratory. The laboratory specializes in defect metrology and failure analysis in semiconductor devices and nanostructures using quantitative cathodoluminescence (CL) microspectrometry.


The emergence of nanophotonic devices appeal for sub-wavelength optical characterization techniques. Various techniques such as scanning near-field optical microscopy (SNOM) or stimulated emission depletion (STED) microscopy... [ view full abstract ]
