A solution-processable erbium-ytterbium codoped complex is synthesized. The absorption and photoluminescence spectra of the complex are observed. The full width at half maximum of the emission spectrum is 80 nm around 1530 nm. A structure of embedded waveguide with the complex as core layer is designed. With an input signal power of 0.3 mW, an optical gain of 5.2 dB at a wavelength of 1550 nm is obtained in a 15-mm-long waveguide when the cladding layer is SU-8. When the cladding layer is polymethyl methacrylate, an optical gain of 6.5 dB is obtained in a 12-mm-long waveguide with an input signal power of 1 mW.
