Recently there has been considerable interest in the field of rare-earth-doped integrated optics because of their potential use in compact and efficient monolithic devices combining the rare-earth laser gain and the large range of integrated optical functions already demonstrated. Recent developments in Nd3+-doped and Er3+-doped glass and LiNbO3 waveguide lasers and optical amplifiers, their application, and future prospects are reviewed briefly.
