Frequency Comb-Based WDM Transmission Systems Enabling Joint Signal Processing

Applied Sciences, 2018
We review the use of optical frequency combs in wavelength-division multiplexed (WDM) fiber optic communication systems. In particular, we focus on the unique possibilities that are opened up by the stability of the comb-line spacing and the phase ...

Optical frequency combs and optical frequency measurements

, 2014
Self-referenced optical frequency combs are nowadays the instrument of choice in time and frequency metrology when dealing with high accuracy and stability measurements of optical frequencies. Beyond this purely measurement activity, they also have new high performance applications, such as low phase noise microwave generation and transfer of spectral ...

An ultra-stable high-power optical frequency comb

APL Photonics
Optical frequency combs are typically generated in the near-infrared wavelength range, where many mode-locked lasers operate. Nonlinear frequency conversion can then be used to extend optical frequency metrology to other spectral regions, such as the ...

Downsampling of optical frequency combs

Journal of the Optical Society of America B, 2018
We demonstrate repetition-rate downsampling of optical frequency combs by way of pulse gating. The reduced repetition rate enables increased pulse energy, facilitating efficient spectral broadening and f-2f interferometry. To explore the technique, we downsample a 250 MHz repetition-rate comb to 25 MHz and detect the carrier-envelope offset frequency ...
