Abstract
The explosive growth of the Internet traffic requires the design of next generation switching systems accommodating huge data-centric traffic at the packet level. All-optical packet switching (OPS) with greater flexibility, granularity and switching capacity is able to meet the complexity of traffic. An all-optical fiber-optic switching device maintains the signal as light, from input to output. Semiconductor optical amplifiers (SOAs) are widely studied as nonlinear elements for high bit rate all-optical switching applications, such as wavelength conversion and regeneration. All optical switches incorporating SOAs have peculiarities like small size, low switching energy requirement and high non linearity. Here simulation of a 4 x 4 optical packet space switch array based on Optically Amplified Suppressed Interference Switches (OASIS) with different data rate has been performed. The OptiSystem version-12 simulator is used to model the structure, it is also used to assess the behavior and performance of this switch array. The simulation of 4x4 space switch array with different bit rate and for different modulation format is done which gives the BER within the acceptable range. Implications of cascadability of this switch array will be analysed which improves the quality and capacity of the existing networks
