Soft-landing and optical characterization of a preselected single fluorescent particle on a tapered optical fiber

Optics Express, 17(26):24234-24243.

Tapered optical fibers offer easy access to the evanescent field of their guided modes which is ideal for sensing applications. We introduce a soft-landing technique utilizing a linear Paul trap to select and place a single microparticle on the surface of a tapered optical fiber. This approach allows on-demand functionalization of fragile nanophotonic components with arbitrary particles, e.g., for advanced nanosensors.
