We report optical trapping of 60 nm Au nanoparticles using photonic crystal slot-cavities with Q's of ∼7200 and 0.3mW of guided power at 1.6µm. Histograms of the cavity transmission are used to quantitatively analyze the trapping dynamics by modeling the back-action of the nanoparticles in the trap.
We experimentally demonstrate that a minute continuous-wave becalms Raman soliton and thus actively suppresses supercontinuum. The effects are characterized in detail by real-time spectrally-resolved statistical analysis enabled by optical time-stretch.
We present a single-photon to single-atom interface, where a heralded single photon generated by Spontaneous Parametric Conversion is absorbed by a single trapped ion, subsequently generating a single Raman-scattered photon that heralds the absorption event.
A lidar system with high tolerance to background light is described. Velocity sensitivity measurements using two different signal processing methods are compared. Sensitivity of −90 dBm is realized for up to 6.9 km/s emulated speeds.
