Abstract
Embedding of end-tapered, thin-cladding fiber bundles for board- level large bandwidth optical clock distribution is proposed and implemented. Fan-outs of 1 to 64- and 128-nodes on a printed circuit board of area 13 X 9 cm2 are experimentally demonstrated. Dispersion measurement shows a 30 picosecond pulse broadening over 30 cm length of the fiber, thereby indicating multi Gb/s clock delivery capability. Power coupling efficiency of 3 dB with coupling nonuniformity of 4.7 - 5.5 dB is observed.
