文摘

The birefringence induced by the electromagnetically induced transparency effect in a \(\hbox {Pr}^{3+}:\hbox {Y}_2 \hbox {SiO}_5\) crystal was studied by using a balanced polarimeter technique. The results show that it is possible to control the polarization state of the output probe beam by adjusting the experimental conditions. Particularly, the coherently prepared \(\hbox {Pr}^{3+}:\hbox {Y}_2 \hbox {SiO}_5\) crystal can serve as a polarization rotator for a linearly polarized input probe beam at the two-photon resonant condition. Such coherent control on the polarization of light should be useful for polarization-based classical and quantum information processing such as all-optical switching, polarization preserving light pulse memory and polarization qubits based on rare earth ion-doped solids.
