Paper Abstract

Semiconductor optical amplifiers (SOAs) are useful nonlinear components, which are the key elements for all-optical gates. This paper is devoted firstly to nonlinear elements based on SOAs. Secondly, a novel configuration using two cascaded SOAs will be presented. Besides the simplicity of this assembling, the gain nonlinearity is accentuated by the mutual gain modulation of the two SOAs which is an interesting feature to improve XGM applications. The reported results point essentially on static characteristics and applications. A spatial evolution of the XGM across the two SOAs cavities is simulated to evaluate and optimize the performances of this configuration. All-optical functions, such as a switch and a NOR gate, will be presented by using two SOAs of 500 μm and 750 μm lengths.
