Traveling-wave electrode electroabsorption modulators toward 100 Gb/s

We present segmented traveling-wave electroabsorption modulators matched to 50 /spl Omega/. The devices show excellent high frequency performance up to 50 GHz, and exhibit a maximum model-extrapolated 3 dBe bandwidth of 90 GHz. Clear eye openings at 50 Gbit/s are presented.
