Image of FIG. 1.
FIG. 1.

A sequence of images showing the process of attaching a single ZnS nanowire to a fiber taper. [(a) and (b)] a fiber taper with a small amount of optical adhesive already applied to it was moved toward a ZnS nanowire; [(c)–(f)] the ZnS nanowire was attached to the fiber taper and lifted off the substrate as the taper was translated.

Image of FIG. 2.
FIG. 2.

[(a) and (b)] field emission scanning electron microscope images of a nanoprobe attached with a single fluorescent microsphere ( diameter) and a nanoprobe attached with multiple fluorescent nanospheres ( diameter), respectively; (c) zoomed-in view of the tip of the two photon nanoprobe shown in (b).

Image of FIG. 3.
FIG. 3.

(a) two-photon fluorescence spectrum of a type I nanoprobe with a single sphere (solid blue curve) and spectrum of ZnS nanowire only (dotted red curve), (b) two-photon fluorescence spectrum of a type II nanoprobe with multiple fluorescent nanospheres ( diameter) (solid blue curve) and spectrum of ZnS nanowire only (dotted red curve).

Image of FIG. 4.
FIG. 4.

(a) Schematic diagram of the experimental system. (b) Measured interferometric autocorrelation trace by using a type I nanoprobe (blue) and theoretical curve (properly scaled and shifted) calculated by assuming a Gaussian pulse profile with a pulse width of 120 fs (full width at half maximum) and a linear chirp parameter of 1.9 (red dots). (c) Interferometric autocorrelation trace obtained by using a type II nanoprobe (blue) and theoretical curve (properly scaled and shifted) calculated by assuming a Gaussian profile with a pulse width of 127 fs (full width at half maximum) and a linear chirp parameter of 2.5 (red dots).
