Fiber Sources and Applications Group

The group's primary thrusts are the development and application of fiber-laser frequency combs to optical clocks, frequency transfer, ranging, and precision spectroscopy. Specific recent work includes development of a robust, fieldable frequency comb, synchronization of distant clocks to femtosecond timing, and the application of “dual-comb spectroscopy” to atmospheric gas detection across open paths.

Optical frequency combs convert a laser source containing a single frequency of light into pulses that include thousands of frequencies. This project aims to develop the technology for a growing list of applications. Using a comb working at optical telecommunications wavelengths, project physicists have transmitted signals from next-generation optical atomic clocks across hundreds of kilometers. They have demonstrated how pairs of combs can increase by a factor of one hundred the speed of infrared spectroscopy for chemical analysis, while also enhancing sensitivity. Frequency combs also promise to provide extremely accurate distance measurements and to assess the quality of high-speed telecommunications signals with unprecedented precision.

Nathan Newbury, Ian Coddington, Esther Baumann, Sean Coburn, Kevin Cossel, Fabrizio Giorgetta and Eleanor Waxman of the Fiber Sources and Applications Group within Applied Physics Division are part of a team that won the 2019 CO-LABS Governor's Awards for High Impact Research Award! Dual Comb Spectroscopy Methane Detection Technology based on Nobel Prize-winning research in Colorado can detect methane emissions as small as a quarter of a human breath from over a mile away. Congratulations to the Fiber Sources and Applications Group and all the members on the team!
