OSA/SPIE, SPRC and Ginzton Lab present "Ultrafast Multidimensional Coherent Spectroscopy of Color Centers in Diamond"
Color centers in diamond are point defects within the diamond host lattice that absorb and emit light at optical frequencies. Besides contributing to the striking visual characteristics of "fancy colored diamond" gemstones, the centers—particularly the negatively charged nitrogen-vacancy (NV) center and silicon-vacancy (SiV-) center—offer a number of possibilities for quantum computation and quantum information processing. In this talk, I will summarize recent work investigating the properties of negatively charged silicon-vacancy centers in diamond using the optical multidimensional coherent spectroscopy (MDCS). Finding suggest a strong influence of strain in determining the presence or absence of radiative coupling in the centers. By extension, the results reveal a new knob for tuning color-center-based photonic devices.
