Nobel Prize Technique on a Chip

Team of scientists at MPQ generate frequency comb with microresonators on a chip for the first time

The frequency comb technique invented at the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, has influenced and advanced basic research as well as laser development and its applications to such an extent that in 2005 its inventor Theodor Hänsch (MPQ) was awarded the Nobel Prize in Physics together with his US-colleague John Hall. The high-precision measuring instruments for determining optical frequencies have meanwhile been made relatively compact and become commercially available. Much handier, however, is the just 75 micrometres in diameter microresonator with which Dr. Tobias Kippenberg and co-workers from the ‘Laboratory of Photonics’ at MPQ succeeded in generating frequency combs (Nature, 20 December 2007). Frequency combs on a microchip could revolutionize time measurement and data transmission techniques. (Excerpt from the press release of MPQ)
