Semiconductor optical amplifier with a reduced noise figure

Summary

A semiconductor optical amplifier for amplifying an optical signal. The amplifier comprises an input for receiving the optical signal and an output for outputting an amplified version of the optical signal. A semiconductor active medium is provided for defining an amplification path extending between the input and the output for amplifying the optical signal as the optical signal propagates along the amplification path. A control means selectively controls the amplified spontaneous emission

Technology Benefits

The innovative SOAs performance is a vital step towards the full integration of thid device in the all-optical telecommunications networks. Currently, erbium-doped-fibre amplifiers (EDFAs) are the main actor on the optical amplifier market thanks to thier good performances. SOAs are far greater in terms of their low-cost, versatility to achieve all-optical signal processing and logical functions, and integrability.
