“…Therefore, there exists a base of knowledge to draw upon for this material as well as a largely unexplained variation in achievable homogeneous linewidths. Our previous investigations into the optical properties of Eu 3+ :Y 2 O 3 transparent ceramics [18,19] measured homogeneous linewidths as narrow as 10 kHz. This enables a high-resolution study of dephasing mechanisms.…”

“…Transparent ceramics were prepared from high-purity Y 2 O 3 (99.999%) and Eu 2 O 3 (99.99%) nanopowders according to the process described in detail in Refs. [18] and [19]. A sintering aid (0.5% ZrO 2 ) was added to some samples.…”

“…By calculating the excitation density of Eu 3+ , ion−ion can be bounded using the ISD coefficient measured for Eu 3+ :Y 2 O 3 (β ISD = 1.3 × 10 −13 Hz / (excited ions cm −3 ) [26]. Given the concentration of the sample (0.5%), the inhomogeneous linewidth (19.5 GHz) [18], and a maximum excitation bandwidth of <1 MHz, ion−ion is bounded above by 700 Hz.…”

“…As a result, systematic studies of different growth conditions can be conducted relatively quickly and inexpensively. In addition, transparent ceramics possessing narrow, homogeneous linewidths are appealing in their own right for technological applications [18]. In particular, transparent ceramics offer a larger flexibility in volume, shape, and composition than single crystals.…”

We identify and analyze dephasing mechanisms that broaden the optical transitions of rare-earth ions in randomly oriented transparent ceramics. The study examines the narrow 7 F0 ↔ 5 D0 transition of Eu 3+ dopants in a series of Y 2 O 3 ceramic samples prepared under varying conditions. We characterize the temperature and magnetic field dependence of the homogeneous linewidth, as well as long-term spectral diffusion on time scales up to 1 s. The results highlight significant differences between samples with differing thermal treatments and Zr 4+ additive concentrations. In particular, several distinct magnetic interactions from defect centers are observed, which are clearly distinguished from the broadening due to interactions with two-level systems and phonons. By minimizing the broadening due to the different defect centers, linewidths of the order of 4 kHz are achieved for all samples. The linewidths are limited by temperature-dependent interactions and by an interaction that is yet to be identified. Although the homogeneous linewidth can be narrowed further in these ceramic samples, the broadening is now comparable to the linewidths achieved in rare-earth-ion-doped single crystals. Thus, this work emphasizes the usefulness of studying ceramics to gain insights into dephasing mechanisms relevant to single crystals and suggests that ceramics may be an interesting alternative for applications in classical and quantum information processing.

Rare‐earth (RE) ion doped crystalline materials have a wide spectrum of applications in lasers, amplifiers, sensors, as well as classical and quantum information processing. The incorporation of RE ions into integrated photonics holds great promise for enriching the designer's toolbox with a view to addressing key performance features not available in existing photonic integration platforms. RE‐ion‐doped thin‐film LiNbO3 (also called RE‐ion‐doped lithium‐niobate‐on‐insulator, RE:LNOI), which inherits nearly all the material advantages as well as nanophotonic integration from the LNOI technology, meets the urgent demands for chip‐integrated laser sources, optical amplifiers, and quantum memories based on LNOI photonics. In this article, a timely review is provided on the development of RE:LNOI photonics in terms of ion‐doping techniques, chip‐integrated lasers, and amplifiers, as well as low‐temperature optical characterizations for quantum photonics. To conclude, some well‐noted topics that may shape the future directions in lithium–niobate integrated photonics are discussed.
