We have investigated the energy transfers in the 1.54- μ m region of (Er,Sc) 2 O 3 epitaxial thin films grown on Si(111). The interplay of the energy transfers between Er ions in the different and the same symmetry sites makes the dynamics com

We demonstrated atomic frequency comb (AFC) quantum memory in 167Er3+:Y2SiO5 under zero magnetic field by using optical frequency comb (OFC), which enables to quickly and easily produce AFCs with high efficiency over a wide bandwidth.

Semiconductor quantum dots provide a spin-coupled system of an electron and nuclei via enhanced hyperfine interaction. We showed that the nuclear spin polarization in single quantum dots can have three stable branches under a longitudinal magnetic fi

Precise spectroscopy of the hyperfine level system of 167Er-doped Y2SiO5 was achieved in the frequency domain. By using an optical frequency comb to stabilize the light source frequency to an accuracy on the order of hertz on a long-term scale, Allan

We investigate the role of nuclear quadrupolar effect on the formation of a transverse nuclear field orthogonal to the injected electron spin in single self-assembled In 0.75 Al 0.25 As/Al 0.3 Ga 0.7 As quantum dots (QDs). In the Hanle effect measure

Hyperfine interaction in a quantum dot produces a spin-coupled system between an injected electron and a few tens of thousands of nuclei in the electron wavefunction. We report here that the double bistable phenomenon of nuclear spin polarization (NS

Experimental studies on the role of nuclear quadrupole interaction (NQI) to the in-plane nuclear field formation are performed in single self-assembled In0.75Al0.25As/Al0.3Ga0.7As quantum dots (QDs). In Hanle-effect measurements, the electron depolar
