Samenvatting

This thesis work presents the cycle of design, fabrication, characterization of a diffractive optical element functionalized as a dispersive element. This element is intended to be used for modes separation from a single mode fibre to an array of guiding cores. The functionality in communication systems is demultiplexing. We start by exploring design routes using the iterative Fourier transform algorithm and gratings relations as tools for diffractive opticsdesign. The design is intended for the telecommunication wavelength range around 1550nm
(i.e. the C-band), and optimization of the DOE is done on the merit of transferred mode shape and location in the output plane. The selected design is fabricated afterwards on a planar fused silica substrate. The exploited fabrication technology is two-photon polymerisation-based direct laser writing. Lastly, the structure is characterised and validated
