“…There are the lumped-element models (Koumans and van Roijen 1996;Leegwater 1996) and the fully distributed time-domain models (Yu et al 1998). Another approach that is well developed is a travelling wave model (Zhang and Carroll 1992;Radziunas 2006;Bandelow et al 2006). Recently Heck et al (2006) presented a model with a lumped-element approach where the propagation of the pulse through the SOA and the SA were calculated using a distributed time-domain model.…”

In this paper a model and simulation results of integrated semiconductor passively modelocked ring lasers are presented. The model includes nonlinear effects such as two-photon absorption and a non-linear refractive index, a logarithmic gain-carrier relation, and concentration dependent radiative and non-radiative carrier recombination rates. The optical bandwidth of the system is controlled by a digital filter. The model has been used to simulate two geometries of ring modelocked lasers. The first is a symmetric design, where the two counter propagating pulses in the cavity experience the same amplification and absorption. The second is an asymmetric design where the differences for the two directions of pulse propagation are maximised. Simulation results show that a symmetrical cavity shows a several times wider window for its operating parameters for stable modelocking.

Modeling of Active Layer and Injection-locking Characteristics inPolarized and Unpolarized Fabry-Perot Laser Diodes (Received January 6, 2012; Revised manuscript February 14, 2012; Accepted February 14, 2012) In this paper, injection-locking characteristics versus active layer structures in Fabry-Perot laser diodes (FP-LD) are compared. TE and TM gain spectra and peak gains versus carrier density in polarized and unpolarized multiple quantum well structures and in an unpolarized bulk structure are calculated. The calculated gain parameters are applied to a time-domain large-signal model to simulate the injection-locking characteristics. The results show that RIN in unpolarized FD-LDs is about 3 dB lower than that in a polarized FP-LD and that the eye characteristics of the unpolarized FP-LD are much better than those of the polarized FP-LD.
