“…A slot passes a node in the optical medium during s t = 1 μ s, which gives a transfer rate of 100 Gbps. Despite that the slots (or the packets in them) are coloured, to greatly decrease the costs, there is only a single, common optical gate/amplifier (SOA) [16] for all wavelengths. This means that a slot can only be dropped in its totality, as the wavelengths are all either amplified or suppressed.…”

We study the quality of frequency response in a noisy optical network. Such a response can be useful in traditional frequencydomain industrial loop controllers. In particular, we analyse a (step, frequency) response of a simulated computer network, where the stimulus is one of the coefficients which regulate the network's strategy of packet transmission, and the response is the network's momentary performance. This way, we find a frequency range, where an instantaneous dependence between the stimulus and the response can direct a self-adaptation scheme of the proposed strategy due to changing network conditions. To stay in the safe limits of the network's behaviour, we make the stimulus weak. We use a bursty traffic model to test the limits of this approach. We use a model of an optical ring of an experimental NGREEN network developed at NOKIA. The discussed technique was capable of optimising the network's behaviour.

“…Steadily maturing photonic integration technologies of improved yield [3]- [5] have led to impressive demonstrations of functional complex circuits [5] and switching architectures [6]- [8], making firm steps towards Medium-Scale (MS) Photonic Integrated Chips (PICs). In this effort, Semiconductor Optical Amplifiers (SOAs) constitute key-signal processing elements due to their proven credentials of high-speed all-optical switching and enhanced maturity level [2], to the point where a plethora of commercial devices are already available.…”

A time-domain solver for the response of a Semiconductor Optical Amplifier (SOA) relying on multigrid numerical techniques and a wideband steady state material gain coefficient is presented for the first time. Multigrid techniques enable the efficient solution of implicit time discretization schemes for the associated system of coupled differential equations, namely the carrier rate equation in the time domain and the signal amplification in the spatial domain, which in turn enable accuracy-instead of stability-restricted time-discretization of the signals. This allows lifting off the limitations of an equidistant spatio-temporal grid for the representation of the incoming signals adopted by traditional explicit SOA models, releasing an adaptive stepsize controlled solver for the dynamic SOA response with dense timesampling under a rapidly varying SOA signal output and scarce time-sampling when negligible changes are observed.
