WDM TRANSMITTER |
摘要 |
A WDM transmitter comprising an array of M pump lasers multiplexed by an MxN multiplexer, in the form of a coupler, and used to feed an array of N optically pumped fiber lasers emitting at wavelengths lambda<SUB>1</SUB>, lambda<SUB>2</SUB>, . . . lambda<SUB>N</SUB>. The parameter M determines the number of pump lasers as well as the number of inputs of the pump-multiplexing coupler and can be smaller or equal to parameter N that determines the number of optically pumped lasers. The fiber laser outputs are passed through N isolators before entering N modulators were the signals are monolithically modulated. The outputs of the modulators are passed through an array of N tunable attenuators. Finally all the individual channel outputs are recombined into a single output in a combiner. The output will typically lead to an optical network. The proposed architecture may also be used for optical amplifiers, especially fiber-based optical amplifiers. |
