46 GB S DEMUX, 50 GB/S MUX, AND 30 GHZ STATIC FREQUENCY-DIVIDER IN SILICON BIPOLAR TECHNOLOGY/

High-speed multiplexers, demultiplexers, and static frequency dividers are key electronic components in future optical broadband communicati on systems, In this paper we present a 50 Gb/s multiplexer, a 46 Gb/s demultiplexer, and a 30 GHz static frequency divider, The IC's were fa bricated in a self-aligning double-polysilicon bipolar technology usin g state-of-the-art production process modules, The achieved results ar e record speeds not only for silicon, but, except for the static divid er, for all semiconductor technologies. The high performance of this c hipset shows that circuits in silicon bipolar technology will play an important role in future multigigabit-per-second fiber-optic communica tion systems, at data rates of 20 Gb/s or even at 40 Gb/s.
