“…In the past, a number of papers containing models for lasers based on three rate equations for the numbers of carriers, photons, and the optical frequency have been published [6]- [9]. Based on these models, properties of transmission systems were simulated [10]- [15]. Recently, the dynamical properties of quantum-well (QW) lasers have been studied by including an additional rate equation for the unconfined carriers in the core region [16]- [19].…”

A laser model based on rate equations for the simulation of high-speed optical access networks using directly modulated lasers is presented. The laser model is implemented into a commercial microwave simulator (Microwave Design System (MDS), Hewlett Packard). The extraction of dc-and smallsignal RF parameters of the laser is described. The laser model is verified by the very good agreement of simulated and measured large-signal intensity and chirp waveforms. Model validity is further confirmed by comparing measured and simulated 10-Gbit/s eye diagrams after up to 100 km of standard fiber.

“…However, in most cases, model validity was only verified by comparing measured and simulated intensity modulation (IM) waveforms. In particular, there are only very few accurate measurements of large-signal time-resolved chirp waveforms for directly modulated laser diodes [1], [15].…”

“…The entire system has been numerically simulated. Pulses at the interferometer input have been obtained in simulations using the density rate equations for photons, carriers and phase [15] with typical parameters for a 1550 nm DFB laser [16], Pulses are generated by gain switching the laser with the current /(t), given by the sum of a Direct Current (DC) term, /BIAS, and a sinusoidal current with amplitude / A MP and frequency/ G s, i.e. /(t) = 'BIAS + /AMP-SÍn(27T/ Gs t).…”

We propose the use of a polarization based interferometer with variable transfer function for the generation of temporally flat top pulses from gain switched single mode semiconductor lasers. The main advantage of the presented technique is its flexibility in terms of input pulse characteristics, as pulse duration, spectral bandwidth and operating wavelength. Theoretical predictions and experimental demonstrations are presented and the proposed technique is applied to two different semiconductor laser sources emitting in the 1550 nm region. Flat top pulses are successfully obtained with input seed pulses with duration ranging from 40 ps to 100 ps.

As the key apparatus, the All optical Wavelength Converter (AOWC) will play an important role in future optical communication and optical signal processing system. In this paper, switching characteristics of wavelength converter based on saturable absorber in semiconductor lasers will be researched. This kind of conversion mechanism possesses some advantage, such as simple structure, low cost, high stability and so on. This paper is organized as follows: Firstly, utilizing rate equations, a new theoretical model on wavelength conversion based on saturable absorber is put forward. Nextly, the frequency modulation response of wavelength conversion will be discussed under the small-signal analysis based on the theoretical model. Lastly, Numerical value solution results will be given out when external signal light injects in saturable absorber region of semiconductor lasers. The characteristics of wavelength conversion are simulated in different optical parameters including the injection current, the input signal optical power and bit rate. Those results are useful to realization and the optimal design of the wavelength converter based on saturable absorber.
