Abstract

The HP LSC2500 2.488-Gbit/s DFB laser diode module has been successfully developed using microwave, laser and fiber models. These models accurately predicted the microwave s-parameters of the laser module and therefore the electrical signal reaching the laser diode. Knowing the electrical signal to the laser, the optical output has been predicted, which leads to the wavelength chirp and therefore the dispersion penalty over long lengths of single-mode fiber at 1550 nm. The predicted optical pulse shapes both before and after the fiber agree closely with the experimental results.
