Rapid multiplex ultrafast nonlinear microscopy for material characterization
Torben L. Purz, Blake T. Hipsley, Eric W. Martin +2
We demonstrate rapid imaging based on four-wave mixing (FWM) by assessing the quality of advanced materials through measurement of their nonlinear response, exciton dephasing, and…
Coherent Interactions Between Silicon-Vacancy Centers in Diamond
Matthew W. Day, Kelsey M. Bates, Christopher L. Smallwood +5
We report coherent interactions within an ensemble of silicon-vacancy color centers in diamond. The interactions are ascribed to resonant dipole-dipole coupling. Further, we demons…
Using silicon-vacancy centers in diamond to probe the full strain tensor
Kelsey M. Bates, Matthew W. Day, Christopher L. Smallwood +5
An ensemble of silicon vacancy centers in diamond (\ce{SiV-}) is probed using two coherent spectroscopy techniques. Two main distinct families of \ce{SiV-} centers are identified u…
Spectral Broadening and Ultrafast Dynamics of a Nitrogen-Vacancy Center Ensemble in Diamond
Albert Liu, Steven T. Cundiff, Diogo B. Almeida +1
Many applications of nitrogen-vacancy (NV) centers in diamond crucially rely on a spectrally narrow and stable optical zero-phonon line transition. Though many impressive proof-of-…
Hidden Silicon-Vacancy Centers in Diamond
Christopher L. Smallwood, Ronald Ulbricht, Matthew W. Day +7
We characterize a high-density sample of negatively charged silicon-vacancy (SiV) centers in diamond using collinear optical multidimensional coherent spectroscopy. By comparin…
Enhanced third-order optical nonlinearity driven by surface-plasmon field gradients
Vasily Kravtsov, Sultan AlMutairi, Ronald Ulbricht +3
Achieving efficient nonlinear optical frequency conversion in small volumes is key for future on-chip photonic devices that would provide a higher-speed alternative to modern elect…
Gigahertz optomechanical modulation by split-ring-resonator nanophotonic meta-atom arrays
Y. Imade, R. Ulbricht, M. Tomoda +4
Using polarization-resolved transient reflection spectroscopy, we investigate the ultrafast modulation of light interacting with a metasurface consisting of coherently vibrating na…
Detection of deep-subwavelength dielectric layers at terahertz frequencies using semiconductor plasmonic resonators
Audrey Berrier, Pablo Albella, M. Ameen Poyli +4
Plasmonic bowtie antennas made of doped silicon can operate as plasmonic resonators at terahertz (THz) frequencies and provide large field enhancement close to their gap. We demons…
