This allows us to describe the spatio-temporal effects due to the thermal dynamics with regard to pattern formation and especially cavity solitons. We consider both the case of a bulk medium in a passive configuration, following a previously introduced modelisation, and the case of a multiple quantum well (MQW) medium in an active configuration, that is, the device is electrically pumped, behaving as an amplifier, following another previously introduced model. We analyse the instabilities affecting the system by performing the linear stability analysis of the homogeneous steady state, and we perform the numerical integration of the equations describing the electric field, carrier and temperature dynamics, and we show the main numerical results. The inclusion of thermal effects introduces a Hopf instability which, in certain region of the parameter space, dominates the behaviour of the system.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.

Optical amplifiers in dynamic networks with all-optical routing 全光路由动态网络中的光放大器

Because the amplifiers saturate on a total-power basis, addition or removal of channels in a multi-access wavelength-routed network will tend to perturb channels at other wavelengths, which share all or part of the route. We present theoretical and experimental results of surviving channel power fluctuations in a cascade of five erbium-doped fibre amplifiers (EDFA) caused by channel addition/removal in networks employing all-optical routing and suggest measures leading to suppression of these power fluctuations. Application of all-optical gain-clamping, pump-power-loss-controlled EDFA and highly inverted amplifiers is discussed in detail.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.
