HIGH DATA RATE SILICON PHOTONIC - CMOS ELECTRONIC MODULES USING COPPER MICROBUMPS

Achieving high data speed (typically Nx25 Gbps) compact optoelectronic modules is now made possible by using Photonic Integrated Circuits (PIC) combined with CMOS electronic drivers. Among the techniques that can be used to combine both circuits, flip-chip assembly based on micro-bumps shows several advantages, for example low RF parasitics and high density compared to wire bonding. Using this technique, it is possible to build low consumption photonic receivers working at 25 Gbps.
