Abstract
As datacom link speeds approach 100 Gb/s per lane, higher complexity modulation formats such as PAM-4, PAM-8, and discrete multi-tone (DMT) have become favored by some despite their frequent need for forward-error correction (FEC) adding unnecessary latency. In this talk, we will describe a new optical-domain equalization scheme that leverages photonic integration to extend bandwidth without adding latency. We will describe our work using an IC-driven segmented electrode Mach Zehnder modulator that exploits this unique feed-forward equalization to generate 60-Gb/s on-off keyed (OOK) non-return-to-zero (NRZ) transmission with BER < 10-12. The approach can deliver high link bandwidths with ultra-low latencies.
