Abstract
Erbium-doped optical fiber amplifiers (EDFA) pumped by 0.98-μm laser diodes exhibit a small noise figure (1) and small temperature-induced variation in amplification compared with pumping by 1.47-μm laser diodes (2). Recently, considerable research interest has focused on 0.98-μm laser diodes (3)-(8).
