Abstract: Source-free Maxwell equations admit three-dimensional solutions with a knotted optical vortex structure. The theoretical evidence naturally gives rise to the question: Could such peculiar fields also exist in nature and in particular, could they be created in a laboratory? Our main objective is to provide an analytic investigation of their characteristic properties, which will provide an insight in how their experimental synthesis could be achieved. A close examination reveals a saddle-shaped local polarization pattern that is transverse everywhere to the vortex line and a broad spectral decomposition. Although the latter feature contradicts the current experimental techniques and therefore complicates their realization; this thesis aims to bring the theory in closer contact with the experiment so to ensure that in the coming years it will be possible to witness an experimentally created knotted optical singularity.
