“…The main reason is the fact that optical interconnections offer an inherently high bandwidth and do not suffer from frequency-dependent loss and electromagnetic interference/ compatibility problems as opposed to electrical interconnections where these problems lead to a significant bandwidth limitation at high frequencies [1]. The use of a hybrid electrooptical board, which contains optical interconnections for the highspeed/bandwidth data transfer and electrical interconnects for the remaining ones, could overcome this problem [2]. The integration of the optical interconnects to the board level can be achieved with the use of a polymer optical layer [3], which contains multimode optical waveguides and other passive optical elements.…”

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.

“…If the information is processed as an optical signal itself, not an electrical signal, then the information processing speed will be increased and it can provide much more convenience by reducing the signal to noise ratio. Therefore the optical communication system will be expected that it will lead the future communication system by using a photonic device [1][2][3][4][5][6].…”

“…Optical printed circuit boards (PCBs) contain an optical layer in addition to the traditional electrical interconnections. Although a rather large number of boardlevel optical interconnect technologies have been developed in the recent years [2,3], optical signaling on PCBs does not yet provide a very cost-effective solution, mainly due to its lack of maturity.…”

Coupling structures for out-of-plane coupling in optical PCBs

et al. 2008

Coupling structures are critical building blocks that have a big influence on the performance of board-level optical interconnections. 45° micro-mirrors deflect the light beam over 90° and are used for out-of-plane coupling in single layer structures and out-of-plane and inter-plane coupling in multilayer structures. Two different approaches are being presented: a micro-mirror that is directly integrated with the multimode waveguides and a discrete coupling element that can be plugged into a cavity in the optical layer. The advantage of the integrated micro-mirror is the high achievable alignment accuracy. The discrete couplers on the other hand have the advantage that they can be characterized and measured prior to the insertion into the optical layer. Both mirror configurations are discussed and the performance is evaluated at wavelength 850nm.
