Last month we discussed how all interconnects will be optical in the data center in five years, but that’s only part of the story. Every optical interconnect needs a laser. The laser provides the ...

A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could ...

Scientists at the UK's National Physical Laboratory (NPL) have published their latest findings on laser frequency stabilization, demonstrating what they call "an unprecedented level of performance ...

Optical technology is well established for long-haul communications, but the distances it serves are shrinking — especially in the data center. Vertical-cavity surface-emitting lasers (VCSELs) already ...

Illustration of a racetrack laser operating under radio-frequency injection. The RF 'wave' radiates throughout the chip and generates multiple frequency-locked tones which circulate the racetrack.
