High-bandwidth density optical I/O for high-speed logic chip on waveguide-integrated organic carrier

Abstract

We demonstrate a high-bandwidth density optical I/O on a waveguide-integrated organic carrier. Each transmitter channel operates at a data rate up to 20 Gb/s for an aggregate value of 240 Gb/s. High-speed and inter-channel crosstalk characterization show that the optical multi-chip module realizes over 10 times higher bandwidth density than conventional optical fiber modules by chip-level packaging and waveguide core pitch reduction, therefore the module supports a nearly 2 Tb/s bandwidth. © 2011 IEEE.
