Paper Abstract

In this paper, characteristics of erbium-ytterbium co-doped phosphate glass waveguide amplifier integrated with multilayer medium thin film filter is designed theoretically, a S-type geometry waveguide structure is used to achieve a long path in a compact chip, and obtained higher gain with lower Er-doped concentration. The multilayer medium thin film filter is utilized to achieve a broader flattening gain bandwidth. The intrinsical gain spectrum is obtained by solving rate and power propagation equations, the effect of transmittance spectrum of thin film filter on flattening gain is discussed. Average gain of about 17dB is obtained between 1535nm and 1565nm with gain difference of below 3dB.
