Raman amplifier system

摘要

A Raman amplifier system (100) comprises an optical wave guide (102) having a crystalline material for guiding an optical signal having a first wavelength. The crystalline material has a Raman wavelength shift. A pump is configured to pump light into the optical wave guide. The pump light has a second wavelength being equal to the first wavelength minus the Raman wavelength shift. An independent claim is also included for generating a Raman gain comprising propagating an optical signal through the optical wave guide, and introducing pump light into the optical wave guide.
