Abstract
The feasibility of a 40 Gb/s subcarrier modulated
optical transmission system using low-cost optoelectronic compo-
nents and CMOS IC technology is presented. The optical channel
impairments are studied. A complete DSP framework is developed
to cancel out the optical channel impairments as well as analog
circuit imperfections. To validate that the 40 Gb/s system can be
implemented in CMOS, an integrated QAM-16 transceiver with
a carrier frequency of 13.32 GHz was designed and fabricated
in a 0.14
