Laser devised for on-chip optical connections
A new 2-µm-high surface-emitting laser for on-chip optical connections could give computers a huge boost in speed and energy efficiency.
Traditionally, edge-emitter lasers are considered as the candidate for on-chip optical links. However, because mirrors are hard to form in these lasers and because the lasers occupy a large chip area, researchers have been challenged to find a practical way to monolithically integrate the mirrors on silicon chips.
