Observation of Photon Echoes from Evanescently Coupled Rare-Earth Ions in a Planar Waveguide
We report the measurement of the inhomogeneous linewidth, homogeneous linewidth, and spin-state lifetime of Pr3+ ions in a novel waveguide architecture. The TeO2 slab waveguide deposited on a bulk Pr3+:Y2SiO5 crystal allows the H34虠1D2 transition of Pr3+ ions to be probed by the optical evanescent field that extends into the substrate. The 2-GHz inhomogeneous linewidth, the optical coherence time of 70±5μs, and the spin-state lifetime of 9.8±0.3s indicate that the properties of ions interacting...[Show more]
