Abstract

Rare-earth dopants are one of the most extensively studied optical emission centers for a broad range of applications such as laser optoelectronics, sensing, lighting, and quantum information technologies due to their narrow optical line width and exceptional coherence properties. Epitaxial doped oxide thin films can serve as a promising and controlled host to investigate rare-earth dopants suitable for scalable quantum memories, on-chip lasers, and amplifiers. Here, we report high-quality epitaxial thin films of Tm-doped CaZrO 3 grown by pulsed laser deposition for infrared optoelectronic and quantum memory applications. We perform extensive structural and chemical characterization to probe the crystallinity of the films and the doping behavior. Low-temperature photoluminescence measurements show sharp radiative transitions in the short-wave infrared range of 1.75–2 μm.
