European H2020 COSMICC Project Breakthroughs 'Will Answer Tremendous Market Needs with a Target Cost per Bit that Traditional Wavelength-Division Multiplexing Transceivers Cannot Meet'
This demonstration opens the way to technology that allows a reduction in the cost, the power consumption and the packaging complexity and opens the way to reaching a very high aggregated data rate beyond terabits per second (Tb/s).
Starting with STMicroelectronics' silicon photonics integration platform, the COSMICC project developed a coarse wavelength division multiplexing (CWDM) silicon-photonics transceiver in a packaged module at 100 Gb/s per fiber. It is scalable to 400 Gb/s and includes 3D assembly of a silicon photonic chip and its electronic control chip. The silicon photonic chip integrated high-performance 50 Gb/s NRZ optical modulators and photodetectors, and a two-channel CWDM multiplexer and demultiplexer. The control electronics was optimized to minimize energy consumption down to less than 6 pJ/bit per channel at 50 Gb/s data rate.
In addition, the new building blocks are essential for addressing the need for terabit-per-second transceivers at low cost and low energy consumption to sustain the exponential growth of data traffic in datacenters and in high performance computing systems," she explained.
COSMICC's technology will answer tremendous market needs with a target cost per bit that traditional WDM transceivers cannot meet," Olivier said.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
