    High-Efficiency PICs Accelerate Telecom Speeds to 40 Tbit/s

    Article obtained from Photonics RSS Feed.

    Using multiple wavelengths to deliver information — all on a single PIC — collaborators from Dublin-based Pilot Photonics and the European photonics innovation incubator ACTPHAST 4.0 have found a way to pack more data into existing internet cables, ramping up speeds to 40 Tbit/s. The speed, the collaborators say, is sufficient to download 5000 Netflix films (standard definition) in a second.

    The approach is an alternative to one that may use optical fibers, and it serves as a new method for splitting up light channels.

    The collaborators used optical combs — a single laser that generates a broad spectrum of equally spaced optical frequencies rather than independent lasers — to enable higher-capacity…
