frequency agile lasers Paper

Low-noise lasers are of central importance in a wide variety of applications, including highspectral-efficiency coherent communication protocols, distributed fibre sensing and longdistance coherent LiDAR. In addition to low phase noise, frequency agility, that is the ability to achieve high-bandwidth actuation of the laser frequency, is imperative for carrier recovery in coherent communications, triangular chirping in frequency-modulated continuous-wave (FMCW) based ranging or any optical phase locking as routinely used in metrology.
