Optical components

HP Sees the Light

12:50 PM -- HP Inc. (NYSE: HPQ) has caught the silicon photonics bug, according to this story from EE Times.

Most of the silicon photonics we've been writing about focus on the data center, trying to find ways to replace masses of copper cables that interconnect boxes. The emphasis is on the potential for integration and automated manufacturing of photonics.

HP is interested in all that, too, but like Intel Corp. (Nasdaq: INTC), it also wants to keep chip and board densities increasing. Optical interconnect could be the key. HP outlined its plans at its own Photonic Interconnect Forum last week.

Among the things HP labs is talking about: free-space and photonic-fiber buses; cheap plastic waveguides; and the possibility of using cheap LEDs instead of Vertical Cavity Surface Emitting Lasers (VCSELs) for optical interconnect.
