Title: Wide band raman amplifier
Inventor: HEADLEY CLIFFORD
IPC: H04B10/29
Filed: 2003-03-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a distributed Raman amplifier which has a flat gain over a wide wavelength range.  <P>SOLUTION: The specification describes a distributed Raman amplifier with multiple pump sources for wide band amplification of wavelength division multiplexed (WDM) signals. It was recognized that using multiple pump sources introduces non-linear effects, such as four wave mixing (FWM). These effects are reduced by multiplexing the pump wavelengths in the multiple pump source. It was also recognized that not all of the pump wavelengths over the wavelength spectrum of the pumps contributes to FWM. Thus fewer than all of the pump wavelengths require multiplexing to eliminate FWM in the multiple wavelength pump source. Various approaches are described to ensure that the pump wavelengths do not interact in FWM in the transmission span. The selected individual pump wavelengths may be either time division multiplexed, or frequency modulated.  <P>COPYRIGHT: (C)2004,JPO
