There has been significant progress since 1990 on development of rare-earth-doped glass integrated optics amplifiers and lasers. Several fabrication processes were utilized to make rare-earth-doped waveguides. Neodymium and erbium doped waveguides were successfully produced, and amplifiers and lasers were demonstrated. Recently, high performance erbium-doped amplifiers in phosphate glasses were achieved. In this paper, we review the progress in development of neodymium and erbium doped lasers and amplifiers.
