Multicore EDFA to realize simultaneous excitation with cladding-pumped technology

We report some recent research activities of multicore EDFAs with cladding-pumped technology. We successfully developed cladding-pumped MC-EDFAs with C-band L-band application, respectively. Cladding-pumped L-band MC-EDFA realized output power of 19 dBm for each core between 1576–1603 nm with 33 % reduced power consumption.
