Abstract
The polarization-dependent absorption and emission spectra of the 4I13/2-4I15/2 transition (λ~1.5 μm) 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 ~20-mW pump power
