Wavelength division multiplexed optical interconnect using short pulses

We demonstrate operation of a wavelength division multiplexed chip-to-chip optical interconnect using surface-normal electroabsorption modulators, and a modelocked laser as a single broadband source. The link was successfully operated at 80 Mb/s. While this rate was limited by the repetition rate of the modelocked source, individual CMOS circuits and optoelectronic devices have been shown to work at data rates approaching 1 Gb/s.
