Controlled Stark shifts in Er\(^{3+}\)-doped crystalline and amorphous waveguides for quantum state storage

Description
Summary:We present measurements of the linear Stark effect on the \(^{4}\)I\(_{15/2} \to\) \(^{4}\)I\(_{13/2}\) transition in an Er\(^{3+}\)-doped proton-exchanged LiNbO\(_{3}\) crystalline waveguide and an Er\(^{3+}\)-doped silicate fiber. The measurements were made using spectral hole burning techniques at temperatures below 4 K. We measured an effective Stark coefficient \((\Delta\mu_{e}\chi)/(h)=25\pm1\)kHz/Vcm\(^{-1}\) in the crystalline waveguide and \((\bar{\Delta\mu_{e}}\chi)/(h)=15\pm1\)kHz/Vcm\(^{-1}\) in the silicate fiber. These results confirm the potential of Erbium doped waveguides for quantum state storage based on controlled reversible inhomogeneous broadening.
