    Stark shift control of single optical centers in diamond
    Tamarat, P ; Gaebel, T ; Rabeau, JR ; Khan, M ; Greentree, AD ; Wilson, H ; Hollenberg, LCL ; Prawer, S ; Hemmer, P ; Jelezko, F ; Wrachtrup, J (AMERICAN PHYSICAL SOC, 2006-08-25)
    Lifetime-limited optical excitation lines of single nitrogen-vacancy (NV) defect centers in diamond have been observed at liquid helium temperature. They display unprecedented spectral stability over many seconds and excitation cycles. Spectral tuning of the spin-selective optical resonances was performed via the application of an external electric field (i.e., the Stark shift). A rich variety of Stark shifts were observed including linear as well as quadratic components. The ability to tune the excitation lines of single NV centers has potential applications in quantum information processing.

    Coherent population trapping of single spins in diamond under optical excitation
    Santori, C ; Tamarat, P ; Neumann, P ; Wrachtrup, J ; Fattal, D ; Beausoleil, RG ; Rabeau, J ; Olivero, P ; Greentree, AD ; Prawer, S ; Jelezko, F ; Hemmer, P (AMER PHYSICAL SOC, 2006-12-15)
    Coherent population trapping is demonstrated in single nitrogen-vacancy centers in diamond under optical excitation. For sufficient excitation power, the fluorescence intensity drops almost to the background level when the laser modulation frequency matches the 2.88 GHz splitting of the ground states. The results are well described theoretically by a four-level model, allowing the relative transition strengths to be determined for individual centers. The results show that all-optical control of single spins is possible in diamond.
