120 GSa/s BiCMOS AMUX for 360 Gbit/s High-Information-Rate Signal Generation Demonstrated in 10 km IM/DD System

Future high-speed optical communication requires continuous increases in both information rate (IR) and symbol rate. An analog multiplexer (AMUX) interleaves individually generated tributaries at lower rates to form an interleaved high-speed signal, which allows to reuse cost- and power-efficient low bandwidth CMOS DACs to obtain a broadband signal. A 120 GSa/s BiCMOS AMUX is designed based on a h...
