Abstract
We present a 10-Gb/s, 1×4 optical link based on a DRAM-integration-ready bulk-silicon modulator for multi-drop CPU-DRAM interconnects. The bulk-silicon modulator operated at 10 Gb/s on a die, and at 5 Gb/s in a QFP package. The 1×4 optical link was limited not by signal integrity but by optical power budget, demonstrating its scalable capacity for the future multi-drop memory bus.
