Laser ablation is extremely well suited for rapid prototyping in a research environment and proves to be a versatile technique delivering high accuracy dimensioning and repeatability of features in a wide diversity of materials. In the paper, we present laser ablation as a fabrication method for micro-machining of arrays of precisely dimensioned U-grooves in dedicated polycarbonate and PMMA plates. The dependency of the performance on various parameters (wavelength, energy density and pulse frequency) will be discussed. The fabricated plates are used to hold optical fibre arrays and are key components in the assembly of 2D optical connectors for short distance optical interconnection.
