Modelisation d'un bus microstructure pour les interconnexions optiques a tres haute densite.

摘要

We present the modeling of a microstructured fiber bus for applications to very high density optical interconnects. The present work is carried out following the criteria listed by the American DARPA agency for the C2OI program, which aims at developing new innovative solutions for the replacement of the electric interconnects. The goal is to optimize the parameters of the bus in order to maximize the achievable density of channels while minimizing the crosstalk between channels as well as the bending losses. The use of optical fiber makes it possible to overcome the problems inherent to electric interconnects. Before undertaking the modeling, we present the selected simulation software, OptiBPM(TM), and we validate its results and their interpretation using published results. We then go on with simulations using our parameters in order to draw our own conclusions on the behavior of the crosstalk and the bending losses. Our results confirm that in order to get optimal results, the parameters of the microstructure must be fitted to the characteristics of the signal, the operating wavelength for example. We also present an alternative geometry of the microstructure's cores. Preliminary simulation results foresee the possibility of preserving the general characteristics of the behavior obtained at the end of our simulations while increasing the size of the cores as compared to the regular geometry.;Keywords.
