Abstract-Polymer multilayer optical interconnections have gained interest over the past few years in view of their ability to increase the integration density, increase the routing flexibility, and make full use of the characteristics of 2-D optoelectronic elements. The alignment between the functional elements in the different optical layers has to be sufficiently accurate in ensuring a high overall efficiency of the system. Numerical simulations have been used as a tool to determine whether laser ablation can be used as an alternative technology for the structuring of the functional elements of optical interconnections into a polymer optical layer. The experimentally achievable alignment accuracies are compared to tolerance ranges for an excess loss ≤ 1 dB obtained from the numerical study. The experimental achievements show that the alignment accuracies fall within the numerical tolerance ranges and have a good reproducibility. Experimental realizations of a two-layer multimode waveguide and inter-and out-of-planecoupling structures are discussed and shown.

“…A critical and relatively unsolved issue consists of the efficient coupling of light to and from PCB-integrated waveguides. The most commonly used approach is the use of 45 • micro-mirrors, which are generally directly integrated in the PCB-embedded waveguides (Glebov et al, 2005;Hendrickx et al, 2007;a;Yoshimura et al, 1997). To enhance the coupling efficiency when using waveguide-integrated micro-mirrors, we investigated a pillar-assisted coupling scheme, in which an optical micro-pillar is placed between a surface-mounted laser/detector and an out-of-plane coupling micro-mirror to compensate for differences in thermal expansion of the materials (Glebov et al, 2006).…”

“…Due to severe frequency dependant physical factors such as crosstalk, power dissipation, packaging density, and electromagnetic interference (EMI); copper interconnections used on existing motherboards are expected to cause drastic bottleneck problems for board-to-board or offchip data bus transfers. Consequently, optical links have been extensively researched for high-speed backplane applications (Glebov, et al, 2005). The most significant benefit that optical interconnects provide over electrical links is the tremendous gain in bandwidth capacity.…”
