On-Chip Single Particle Spectroscopy

We demonstrate on-chip optical trapping of micron-sized dielectric spheres using supercontinuum light and silicon nitride waveguides. The broadband source enables scattering spectroscopy to be performed on single particles trapped by a high-confinement waveguide.
