Complete crystal field calculation of Zeeman-hyperfine splittings in europium
Kieran M. Smith, Michael F. Reid, Matthew J. Sellars +1
Computational crystal-field models have provided consistent models of both electronic and Zeeman-hyperfine structure for several rare earth ions. These techniques have not yet been…
Optical and Zeeman spectroscopy of individual Er ion pairs in silicon
Guangchong Hu, Rose L. Ahlefeldt, Gabriele G. de Boo +6
We make the first study the optical energy level structure and interactions of pairs of single rare earth ions using a hybrid electro-optical detection method applied to Er-implant…
Sub-megahertz homogeneous linewidth for Er in Si via in situ single photon detection
Ian R. Berkman, Alexey Lyasota, Gabriele G. de Boo +9
We studied the optical properties of a resonantly excited trivalent Er ensemble in Si accessed via in situ single photon detection. A novel approach which avoids nanofabrication on…
Initialisation protocol for efficient quantum memories using resolved hyperfine structure
James Stuart, Morgan Hedges, Rose Ahlefeldt +1
We describe a quantum memory spectral preparation strategy that maximises memory efficiency and bandwidth in materials such as 167 Er3+:Y2SiO5 in a high field regime, where the hyp…
