Abstract

The optical frequency sweep of an actively linearized, ultra-broadband, chirped laser source is characterized through optical heterodyne detection against fiber-laser frequency combs. Frequency sweeps were measured over approximately 4.7 THz bandwidths from 1530 nm to 1570 nm. The dominant deviation from linearity was quadratic resulting from the residual dispersion of the fiber delay used as a reference for the chirp linearization. Removing the low-order dispersion effects, the residual chirp nonlinearity was less than 60 kHz rms and the measured chirp rate was consistent with an uncertainty of less than 15 parts per billion.
