We investigate new routing and wavelength assignment algorithms considering as constraints physical impairments that arise in transparent networks. Accounting both linear and nonlinear impairments we propose a scheme that integrates the routing and wavelength assignment to achieve an optimal combination of physical and networking performance.

We demonstrate the applicability of quantum-dot semiconductor-optical-amplifier based wavelength converters to the implementation of an ultra-high speed optical packet switching buffer. The buffer architecture consists of cascaded programmable delay stages that fully utilize the available wavelengths and thus minimize the number of wavelength converters(More)
