外文摘要：A novel quantum dots (QDs) optical fiber amplifier was proposed and demonstrated.It was fabricated by dipcoating the PbSe QDs doped sol onto the taper region of fiber coupler.The PbSe QDs was synthesized according to a colloidal method.A lower refractive index sol was also synthesized as the host of PbSe QDs.A standard single mode fiber was used to make the fusion tapered fiber coupler which had double input and output ports.With the simple structure, a signal and a pump can be injected into the amplifier and excite the PbSe QDs through evanescent wave.The experimental results indicated that the amplified light wave was observed at 1 550 nm wavelength with 980 nm wavelength laser diode as pump.
