Laser Built on a Silicon Chip

Facebook X LinkedIn Email
SINGAPORE, April 2, 2012 — A laser with a novel microloop mirror (MLM) design fabricated on a silicon chip uses III-V semiconductor materials — a step forward for high-speed optical communications and interconnects on electronics chips. Active optical fibers with silicon photonic chips carry much more information for data interconnects than copper cables. Silicon could be the material of choice for wiring lab-on-a-chip devices, but for its poor ability to emit light. Now, scientists at the A*Star Data Storage Institute have successfully built a laser on top of a silicon chip, bonding III-V...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
