Abstract

A novel hybrid C+L band EDFA/RFA is designed to share the 1480 nm pump laser(s). The concepts are based on three-level amplification mechanism for the C band EDFA and Raman shift amplification mechanism for the L band RFA, respectively. It has the advantage to simplify the pump source design. The optimum splitting ratio for the pump power is 1:29 for EDFA/RFA. The hybrid C+L band EDFA/RFA, with features of wide bandwidth, flattened gain and low NF, may find vast applications in WDM system and lightwaev transmission.
