Abstract

A method for generating a high-intensity light source at a probe tip, the method includes exciting a TM0 mode of a surface plasmon polariton (SPP) in a sharp-tip metal nanowire (AgNW) waveguide with a linearly-polarized mode (LP01) in a tapered optical fiber (OF); and compressing the TM0 mode through a chemically-sharpened taper to a tip apex of the sharp-tip silver nanowire (AgNW).
