This paper will briefly outline the technology related to CMOS photonics, and will then discuss systems design aspects
and experimental results from the construction of a 4 wavelength WDM transceiver with each channel running at
10Gbps. Optics including mux/demux, modulation and optical monitoring taps were monolithically integrated into the
0.13 micron CMOS die, alongside the PMD circuitry used for modulator drivers and receiver amplification. A BER of 10-12
was achieved on all 4 channels.
