Abstract

High-coupling (kl= 3.0) phase-shifted DFB lasers are studied using a transmission-line laser model (TLLM), which includes spatial hole burning (SHB), the material gain spectrum, refractive index dependence on carrier concentration, and random spontaneous emission. Good agreement for CW spectra is shown with other models and experimental results. Dynamic simulations of laser transients show SHB-in-duced deterministic mode hopping and chirping at moderate output powers. The effects of mode hopping and chirping on system performance are studied using a laser model combined with a fiber model.
