Autor: Zhang, S., Lučić, N., Galland, N., Targat, R. Le, Goldner, P., Fang, B., Seidelin, S., Coq, Y. Le

Publikováno v: [J]. Applied Physics Letters, 2020, 117(22): 221102

We report a series of measurements of the effect of an electric field on the frequency of the ultranarrow linewidth $^7F_0 \rightarrow$ $^5D_0$ optical transition of $\rm Eu^{3+}$ ions in an $\rm Y_2SiO_5$ matrix at cryogenic temperatures. We provide

Material strain has recently received growing attention as a complementary resource to control the energy levels of quantum emitters embedded inside a solid-state environment. Some rare-earth ion dopants provide an optical transition which simultaneo

Microscale crystalline rare-earth doped resonators for strain-coupled optomechanics

Autor: Motte, J. F., Galland, N., Debray, J., Ferrier, A., Goldner, P., Lučić, N., Zhang, S., Fang, B., Coq, Y. Le, Seidelin, S.

Rare-earth ion doped crystals for hybrid quantum technologies is an area of growing interest in the solid-state physics community. We have earlier theoretically proposed a hybrid scheme of a mechanical resonator which is fabricated out of a rare-eart

Double-heterodyne probing for ultra-stable laser based on spectral hole burning in a rare-earth doped crystal

Autor: Galland, N., Lucic, N., Zhang, S., Alvarez-Martinez, H., Targat, R. Le, Ferrier, A., Goldner, P., Fang, B., Seidelin, S., Coq, Y. Le

Publikováno v: Optics Letters, 45, 1930 (2020)

We present an experimental technique for realizing a specific absorption spectral pattern in a rare-earth-doped crystal at cryogenic temperatures. This pattern is subsequently probed on two spectral channels simultaneously, thereby producing an error

Accurate laser frequency locking to optical frequency combs under low-signal-to-noise-ratio conditions

Autor: Guo, C., Favier, M., Galland, N., Cambier, V., Álvarez-Martínez, H., Lours, M., De Sarlo, L., Andia, M., Targat, R. Le, Bize, S.

Publikováno v: Rev.Sci.Instrum. 91, 033202 (2020)

We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low to accommodate other methods. Our method is typically orders of magnitu

Mechanical tunability of an ultra-narrow spectral feature with uniaxial stress

Autor: Galland, N., Lucic, N., Fang, B., Zhang, S., Letargat, R., Ferrier, A., Goldner, P., Seidelin, S., Coq, Y. Le

Publikováno v: Phys. Rev. Applied 13, 044022 (2020)

Rare-earth doped crystals have numerous applications ranging from frequency metrology to quantum information processing. To fully benefit from their exceptional coherence properties, the effect of mechanical strain on the energy levels of the dopants
