The laser exhibits frequency excursion greater than 900 MHz at up to 1 MHz triangular chirp rate with a nonlinearity of less than 1.5%.falseChirpElectro-optical waveguidesPhotonicsTime-frequency analysisSub-MHz linewidth, FMCW photonic integrated blue lasertext::conference output::conference proceedings::conference paper
