Transferring Data with Many Colors of Light Simultaneously

Editor's note:

Our recent Nature Photonics publication, "Massively scalable Kerr comb-driven silicon photonic link" was highlighted in an article by Columbia Engineering.

June 29, 2023

In a study published today in Nature Photonics, researchers at Columbia Engineering demonstrate an energy-efficient method for transferring larger quantities of data over the fiber-optic cables that connect the nodes. This new technology improves on previous attempts to transmit multiple signals simultaneously over the same fiber-optic cables. Instead of using a different laser to generate each wavelength of light, the new chips require only a single laser to generate hundreds of distinct wavelengths of light that can simultaneously transfer independent streams of data.
