Erbium-doped fiber amplifier (EDFA) is considered as the most deploye d fiber amplifier as its amplification window coincides with low loss telecommunication windows at 1550nm. 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 mete rs of fiber,and can be integrated with other photonic devices potentially,such a s switches,couplers and splitters. In this paper,we synthesize an erbium-ytterbium complex which has good so lubility in an organic solvent cyclopentanone.The doping mass ratio of Er³⁺ ionsinth e complex can be up to 10.8%. This complex can be directly used to fabricate films by a spin coating method.A tomic force microscope (AFM) is used to characterize the film.The surface roughness of the c omplexes film is about 0.745nm.The fluorescence emission spectrum shows that the full width at half ma ximum (FWHM) is about 60nm.We propose and implement the all-polymer waveguide amplifiers.For input signal power of ~0.2mW and 980nm waveleng th pump power of ~220mW,an o ptical gain of 2.7dB at 1535nm is obtained from a 3.2cm l ong sample.
