Abstract
Official abstract text for this publication.
A Raman pump may include a dual output laser configured to output two optical signals; a delay interferometer configured to delay a first of the two optical signals to decorrelate the two optical signals from each other; and a combiner configured to combine the delayed first of the two optical signals and a second of the two optical signals to provide a Raman amplification signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A Raman pump, comprising: a laser that has first and second facets, the laser supplying a first optical signal from the first facet and a second optical signal from the second facet; a delay interferometer that receives the first optical signal, such that the first optical signal is decorrleated relative to the second optical signal; a combiner configured to combine the delayed first signal and the second optical signal to provide a Raman pump signal; an…
