In this work, we report on the optical and spectroscopic optimization of Al2O3:Er3+ for the development of amplifiers and lasers by providing details on optical processes in the material such as luminescent lifetimes, signal enhancement, and propagation and absorption losses. In this manner we intend to optimize the host material for favourable Er3+ transitions to maximize the available net gain at 1550 nm, when pumped at 1480 nm. By measuring and tracking a variety of parameters across fabrication and treatment steps, ideal methods are discovered for maximizing optical gain in Al2O3:Er3+ waveguides.
