AlGaAs/GaAs HBT IC's for high-speed lightwave transmission systems

Abstract

The implementation of multigigabit-per-second optical communication systems requires many high-speed electronic circuit components that meet stringent performance requirements. Several important research prototype circuits for fiber-optic transmission, implemented in a baseline AlGaAs/GaAs HBT process, are discussed. These include a 20 Gb/s decision circuit, a 27 Gb/s 1:2 demultiplexer, a 30 GB/s 2:1 multiplexer, a 27 Gb/s 4:1 multiplexer, and a 11 Gb/s laser driver IC.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
