The most recent drastic advancement in nanotechnology has paved the path towards the investigation of many extreme nano-optical effects. There, optical singularities, i.e., the very spatial points where physical parameters describing electromagnetic fields are undefined, have been attracting growing attention from both the physics and engineering communities, for their potential applications in manipulating and trapping microparticles, optical communication and super resolution, to name a few.

The very objective of this doctoral study is, based on a solid theoretical understanding, to design plasmonic/dielectric nanostructures to efficiently exploit structured light in the near field regime of the aforesaid structures and their associated optical singularities, including, phase singularities, polarization singularities, to name a few. The theoretical study on structured light and optical singularities will be performed at the electrical engineering department of KU Leuven, samples will be prepared in collaboration with IMEC (Dr. Niels Verellen), and the near field characterization will be conducted at the physics department of KU Leuven (Dr. Kuo Zhong).
