Just below threshold , consistel1t to theoretical analysis , there are numbers of comb - like narrow linewidth lights due to resonating of ifltr8 - cavity ase light . novel experimental results of the erbium - doped - fiber ring resonator behaviors operating near threshold are reported in the chapter 首先理論分析了當有源環(huán)形腔無注入光,且有源光纖環(huán)形腔在閾值以下時,由有源腔內(nèi)ase輸出光表現(xiàn)出的腔輸出特性。
