Abstract: Comprehensive numerical simulations with the transmission-line laser model (TLLM) are used to compare the behavior of gain-coupled DFB lasers with index-coupled DFB lasers fabricated from identical materials. These simulations compare slope efficiency, threshold current, spectra, smallsignal modulation bandwidth, maximum-intrinsic modulation bandwidth, large-signal transient response and chirp, relativeintensity-noise (RIN) spectra, and feedback sensitivity for coherence collapse. In most cases gain-coupled la…
