A low power 2 x 28 Gb/s electroabsorption modulator driver array with on-chip duobinary encoding

Tijdschriftbijdrage - Tijdschriftartikel Conferentiebijdrage

An integrated 2 x 28 Gb/s dual-channel duobinary driver IC is presented. Each channel has integrated coding blocks, transforming a non-return-to-zero input signal into a 3-level electrical duobinary signal to achieve an optical duobinary modulation. To the best of our knowledge this is the fastest modulator driver including on-chip duobinary encoding and precoding. Moreover, it only consumes 652 mW per channel at a differential output swing of 6 V-pp.
