摘要：

The polarization-dependent absorption and emission spectra of the I-4(13/2)-I-4(15/2) transition (lambda approximately 1.5 mum) in single crystal bulk Er:LiNbO3 have been measured. Low-temperature (10 K) measurements of the Stark split energy levels of these two manifolds indicate at least two Er3+ sites. McCumber theory is applied to determine the Er:LiNbO3 absorption and emission cross sections. These values are used to calculate the gain characteristics of Er:LiNbO3 channel waveguides. Calculations indicate that a gain of 10 dB is achievable in a waveguide of several centimeters using approximately 20-mW pump power.
