Протокол оптической памяти ROSE в волноводе кристаллa Tm : YAG

In this work, optical spectroscopy of thulium ions in a single-mode optical waveguide fabricated in a Tm3+:Y3Al5O12 crystal using the femtosecond laser printing method was carried out and an optical quantum memory protocol was demonstrated in a revival of silenced echo scheme. An analysis of the experimental data indicates the presence of instantaneous spectral diffusion at a thulium ion concentration of less than 0.01%, a weak effect of imperfections in the formed waveguide on the lifetime of the optical memory, and indicates the possibility of achieving a high efficiency of input signal recovery in the implemented waveguide scheme of the protocol.
