摘要：
This study demonstrates a broadband gain-clamped and gain-flattened dispersion-compensated Raman/erbium-doped fiber hybrid amplifier that recycles residual Raman pump power using a single fiber Bragg grating for wavelength-division multiplexing systems. The optimum gain-clamped wavelength was 1564 nm. A gain variation of less than 0.21 dB can be achieved from 1525 to 1625 nm, and the dynamic input power exceeds 18 dB, ranging from -20 to -2 dBm. Further, a gain ripple of +/- 1.75 dB can be achieved from 1530 to 1595 nm. (C) 2012 Society of Photo-Optical Instrumentation Engineers (SPIE). [DOI: 10.1117/1.OE.51.1.015002]
