My research covers a broad area encompassing experimental and theoretical nonlinear optics (both warm and cold vapors), ultra-cold quantum gases, gaseous phase quantum electronics, micro/nano-nonlinear optics and photonics (guided-wave nonlinear optics in novel structures). Recent works include experimental demonstrations of a very weak light polarization gate with unit fidelity, fast modulation of high-fidelity phase gates and optical logic operations, novel schemes for ultra-sensitive magnetic field detection (atomic magnetometers), novel micro-/nano-photonic structures and applications. These research efforts support NIST’s quantum computing initiative (quantum gates) and NIST’s work on precision magnetic field detection (precision metrology of magnetic fields). My underlying goals are to uncover novel and exotic nonlinear optical effects and processes through fundamental research and then apply these new effects and knowledge to further NIST’s precision metrology efforts.
