Abstract

Laser ablation is extremely well suited for rapid prototyping and proves to be a versatile technique delivering high accuracy
dimensioning and repeatability of features in a wide diversity of materials. In this paper, we present laser ablation as a
fabrication method for micro machining of arrays consisting of precisely dimensioned U-grooves in dedicated
polycarbonate and polymethylmetacrylate plates. The dependency of the performance on various parameters (wavelength,
energy density and pulse frequency) is discussed. The fabricated plates are used to hold optical fibres by means of a UV-curable
adhesive. Stacking and glueing of the plates allows the assembly of a 2D connector of plastic optical fibres for short
distance optical interconnects.
