【Abstract】 The future of the application of erbium doped fiber amplifier is discussed. The principle of amplification by Er-doped fiber is presented. The optimum design of fiber parameters is fulfilled with the three-level energy model of Er3+ ions,and the Er-Al codoped fiber with excellent optical properties are produced by MCVD process.更多还原
