Datacom-dedicated optical multiplexer achieves record stability

Leti researchers teamed up with two manufacturers to produce an optical multiplexer for datacoms (links from 1 meter up to 10 km) as reliable as its current competitors. This in itself is a great achievement. Even more impressive, however, is that the researchers actually improved reproducibility for each batch of wafers. The research, which leveraged the resources of IRT Nanoelec, resulted in prototypes that boast losses of 3 dB, insertion error rates of 35 dB, and a transmission dispersion comb of only 0.8 nm.

The researchers are now readying the component for industrial-scale manufacturing, fine-tuning things like improvements to the materials and ways to reduce losses and energy consumption of the optical connection. The multiplexer will be integrated into a datacom transmitter card that will include a III-V laser source/modulator.
