Paper Abstract

All-optical header recognition using a tree-structure is reported for a three-bit address. Each bit of a three bit header is read using an optical Sagnac AND gate and the outcome is used to control each level of the three level tree-structure switch. Traffic at 10 Gb/s (payload) is directed through the switch and each possible address outcome is validated. Reflective semiconductor optical amplifiers (RSOAs) are used as the 1 x 2 space switch at each node of the tree-structure switch. A noise propagation analysis that considers mostly amplified spontaneous emission noise is presented. This analysis takes into account the saturation power of the SOAs, their noise figure, the gain of each SOA and the coupled optical power. It is concluded that large switches based on semiconductor optical amplifiers can be constructed using cascaded SOAs.
