JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Engineers from Vanderbilt University developed a method of simultaneously transmitting two types of optical signals across a single chip. The work may enable a dramatic increases in the volume of data a silicon chip can transmit over any period of time, directly supporting “lab-on-a-chip” capabilities. Engineers design waveguides to work at a single frequency of light, typically 1550 nm, Joshua Caldwell, associate professor in Vanderbilt’s Department of Mechanical Engineering, told Photonics Media. The number of waveguide channels, limited by the amount of space on a...Read full articleRelated content from Photonics MediaArticlesHigh Harmonics Reveal Nonlinear Light-Matter Interaction DynamicsPhysicists from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have illuminated, with laser light, the atomic motions of atoms and electrons contained within a solid.
