Abstract

We present our effort to construct an optoelectronic interconnection layer for Cray supercomputer board for board-level fast optical clock signal distribution. The optical interconnection layer under investigation employs optical channel waveguides with surface-normal waveguide couplers. The difficulties associated with the complicated 3-D multiple alignments are significantly reduced through the parallelism among the surface-normal fanout beams and the unique planar device feature. One-GHz optical clock signal is demonstrated experimentally with a guided-wave interconnection length of 45 cm. Some new techniques to fabricate multimode optical channel waveguides and 2-D array of surface-normal waveguide holographic gratings on board- level are also presented.
