摘要

The 1.53 mu m gain characteristics of ErxYb(Y)(2-x)SiO5 nanowire and film material waveguide amplifiers have been investigated considering the upconversion effect by solving rate equations and propagation equations. The gains of ErxYb(Y)(2-x)SiO5 nanowire waveguides have a significant enhancement compared with those of film material waveguides due to low propagation loss and long photoluminescence lifetime. The cooperative upconversion (CUC) effect plays a significant role in the simulation. The maximum 27 dB/mm gain for a 1 mm length ErxYb(Y)(2)-xSiO(5) nanowire waveguide was obtained without CUC, and only about 2 dB/mm gain was obtained with CUC. However, the low thresholds of 10.7 and 0.7 mW, respectively, for the ErxY2-xSiO5 and ErxYb2-xSiO5 nanowire waveguides amplifiers were observed with CUC by analyzing the relation between optical gain and the Er/Yb/Y concentration, waveguide length, waveguide cross section area, energy-level lifetime, and pumping power coefficients. The low threshold is two to three orders of magnitude lower than the threshold used in thin film experiments. (c) 2015 Optical Society of America
