Intel adds multi-channel lasers to its silicon photonics toolbox

Intel has developed an 8-lane parallel-wavelength laser array to tackle the growing challenge of feeding data to integrated circuits (ICs).

Optical input-output (I/O) promises to solve the challenge of getting data into and out of high-end silicon devices. 

These ICs include Ethernet switch chips and 'XPUs', shorthand for processors (CPUs), graphics processing units (GPUs) and data processor units (DPUs).

The laser array is Intel's latest addition to its library of silicon photonics devices.

NeoPhotonics to expand its tunable laser portfolio

Part 1: Tunable lasers

NeoPhotonics will become the industry's main supplier of narrow line-width tunable lasers for high-speed coherent systems once its US $17.5 million acquisition of Emcore's tunable laser business is completed. Gazettabyte spoke with Ferris Lipscomb of NeoPhotonics about Emcore's external cavity laser and the laser performance attributes needed for metro and long haul.
