Plasmonic Modulator IM/DD Transmitter Operating at 222 GBaud for Intra-Datacenter Applications

Heni, Wolfgang, Journal of Lightwave Technology 38.9 (2020): 2734-2739.

We present a plasmonic modulator IM/DD transmitter operating at 222 GBaud for ultra-fast intra-datacenter applications. This high-speed transmitter enables >200 Gb/s OOK for short-reach transmission and >177 Gb/s over 120 m of standard fiber, overcoming chromatic dispersion limitations.

Fig. 1. 222 GBd transmitter assembly consisting of an InP DHBT 2:1- digital selector (SEL) and plasmonic organic hybrid (POH) Mach–Zehnder modulator (MZM) on silicon photonics. The RF electrodes of the modulator are ribbon-bonded to the output stage of the SEL. The assembly requires less than 2.1 × 1.5-mm².
