摘　　要：合成了一种新型Er3+-Yb3+共掺配合物Er1.2Yb0.8(PBa)6(Phen)2,在有机溶剂环戊酮中有具良好的溶解性,Er3+离子在材料中的质量百分比掺杂浓度可达10.8%。这种配合物可以直接旋涂成膜,用原子力显微镜(AFM)测得配合物薄膜表面粗糙度为0.745nm。荧光发射谱的测试表明,配合物的荧光半高宽(FWHM)为60nm。以PMMA基片为衬底,制备了稀土掺杂全聚合物光波导放大器,且当泵浦光波长为980nm、功率为200mW和信号光功率为0.2mW时,在3.2cm长的样品中获得了2.7dB@1 535nm的相对增益。Erbium-doped fiber amplifier （EDFA） is considered as the most deployed fiber amplifier as its amplification window coincides with low loss telecommunication windows at 1550 nm. However,EDFAs are incompatible with miniature and integrated optical devices in acess and home network applications. Compared with EDFAs,erbium-doped waveguide amplifier （EDWA） provides a higher gain in a much smaller size waveguide rather than several meters of fiber,and can be integrated with other photonic de- vices potentially,such as switches,couplers and splitters. In this paper,we synthesize an erbium-ytterbi- urn complex which has good solubility in an organic solvent cyclopentanone. The doping mass ratio of Era＋ ionsinthe complex can be up to 10.8%. This complex can be directly used to fabricate films by a spin coating method. Atomic force microscope （AFM） is used to characterize the film. The surface roughness of the complexes film is about 0. 745 nm. The fluorescence emission spectrum shows that the full width at half maximum （FWHM） is about 60 nm. We propose and implement the all-polymer waveguide amplifiers. For input signal power of -0.2 mW and 980 nm wavelength pump power of 220 roW,an optical gain of 2.7 dB at 1535 nm is obtained from a 3.2 cm long sample.
