Abstract

Gain and output power as a function of pump power has been calculated for short Er/Yb doped single mode fibers for various fiber parameters. The calculation shows (i) small signal gain increases with increasing Er concentration, (ii) long fiber lengths provide both higher gain and higher output, (iii) calculated gain is larger for higher Er emission cross section, and, (iv) >25 dB gain is feasible for 5 cm long fiber for Er and Yb concentrations of 3 X 10²⁶ m^-3and 1.2 X 10²⁷ m^-3.
