Erbium/ytterbium co-doped optical waveguide amplifier in soda-lime glass by silver ion exchange

We have described the experimental results of the gain characteristics of Er/Yb co-doped optical waveguide amplifiers in soda-lime glasses fabricated by the silver ion exchange method. Silica glasses are attractive because of their superior chemical resistance and compatibility to optical fibers. Measured absorption and fluorescence spectra are shown. A net gain of 4.34 dB and gain coefficient of 1.55 dB/cm was achieved for 28 mm long waveguide with pump power of 90 mW.
