Abstract :
A new, dynamic, time-domain, numerical model for external cavity lasers, based on the transmission-line laser model (TLLM), is introduced. This is able to show the evolution of spectra from large-signal modulated devices, even when the modulation pulsewidth is less than the external cavity round-trip delay. The model is demonstrated using short and long dispersionless cavities. Results in the time and spectral domains are in agreement with those of previous theoretical and experimental work
