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 ...

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.
