Abstract :
We present the design of discrete out-of-plane coupling components featuring a micromirror for 90° beam deflection in multimode optical interconnections at the printed circuit board level. We investigate the Goos-Hanchen shift that occurs upon total internal reflection at a 45° micromirror and assess the influence of applying a metal reflection coating on the micromirror as well as the tolerance for mechanical misalignments using nonsequential ray tracing simulations. Finally, we compare the simulated performance with experimental measurements on out-of-plane coupling components prototyped with deep proton writing.
