Lipson Team Develops Microcomb Source On-Chip for Modern Data Centers

Researchers from the Columbia University School of Engineering and Applied Sciences have developed a method to create a high-power frequency comb that avoids the need for large and expensive lasers and amplifiers. The team’s discovery enabled the researchers to brings the power of the frequency comb on-chip, yielding a compact, high-power, multiwavelength light source. The researchers believe that the developed approach and system could find use in state-of-the art data centers, which are already using fiber optic links to transport data, yet still typically rely on single-wavelength lasers.  Read Article
