| description | High interconnection density associated with current electronics products poses certain challenges in
designing circuit boards. Methods, including laser-assisted microvia drilling and surface mount
technologies for example, are being used to minimize the impacts of the problems. However, the
bottleneck is significantly pronounced at bit data rates above 10 Gbit/s where losses, especially those due
to crosstalk, become high. One solution is optical interconnections (OI) based on polymer waveguides.
Laser ablation of the optical waveguides is viewed as a very compatible technique with ultraviolet laser
sources, such as excimer and UV Nd:YAG lasers, being used due to their photochemical nature and
minimal thermal effect when they interact with optical materials. In this paper, the authors demonstrate
the application of grey relational analysis to determine the optimized processing parameters concerning
fabrication of multimode optical polymer waveguides by using infra-red 10.6 mm CO2 laser micromachining
to etch acrylate-based photopolymer (Truemode™). CO2 laser micromachining offers a low
cost and high speed fabrication route needed for high volume productions as the wavelength of CO2
lasers can couple well with a variety of polymer substrates. Based on the highest grey relational grade,
the optimized processing parameters are determined at laser power of 3W and scanning speed of
100 mm/s. |
