New technique to trap soundwaves and light on a chip in large-scale circuits

In recent decades, chips and electronic devices have become exponentially smaller and faster. Engineers have nearly reached the limits of traditional electronics and are now in the process of transitioning from electronics to photonics, using light instead of electrons. At this scale, all kinds of new challenges arise. For example, the smallest interferences or quantum effects can distort signals and render them unusable. Now, a research team from the University of Twente have added a new soluti...
