CEA-Leti announces demo of full data-transfer silicon photonics module delivering 100 Gb/s and develops building blocks for Tb/s

The demonstration was a fully packaged CWDM optical transceiver module with data transfer of 100 Gb/s per fiber with a low-power-consumption electronic chip co-integrated on the photonic chip. This silicon-photonics-based transceiver multiplexes two wavelengths at 50 Gb/s and is designed to meet the ever-increasing data-communication demands and energy use of data centers and supercomputers – see news release below and attached image.

The EU H2020 project, COSMICC, further developed all the required building blocks for a transmission rate of 200 Gb/s and beyond without temperature control with four 50-Gb/s wavelengths and by aggregating a large number of fibers.

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).
