Title:
RAMAN FIBER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO2002007274
Kind Code:
A3
Abstract:
A method and system by which a wide bandwidth continuous wave (CW) or substantially continuous wave composite (SCWC) pump with a flat spectrum is utilized to amplify an information-carrying signal. By using a wide bandwidth CW pump, substantially no ripple is introduced to the signal being amplified by the Raman amplifier.
