Integrated Silicon Photonics Research
Integrated Silicon photonics is an emerging area of research and development and is considered the enabler of yet higher data rates (>40-100 Gbps) for next-generation computing, 'green' energy-efficient data centers, LANs, and on-chip as well as off-chip interconnects. The optoelectronic industry and academia have demonstrated high performance individual optical and electro-optic devices in the last decade. However, their true potential can only be realized when complex integrated optoelectronic circuits are realized on a CMOS-like platform, in a paradigm similar to the semiconductors industry, where the circuit design is decoupled from the device R&D.
Our group is exploring high-speed Mixed-Signal circuit design which combines the high optical bandwidth and signal pre-processing functionality of Silicon Photonics with the well-established CMOS signal-processing paradigms, all on the same chip. Successful demonstration of this effort will lead to spin-off projects including high-speed interconnects, >10 GHz sampling-rate ADCs, Bio-sensing (DNA/RNA detection), biomedical diagnostics, photonic network-on-chips (NoCs), and photonic-assisted signal-processing concepts in RF/Microwave systems.
