  • REMOTE-EXCITATION TIP-ENHANCED RAMAN SPECTROSCOPY (TERS) PROBE FOR NANOSCALE TERS IMAGING
    Publication number: 20220042917
    Abstract: A method is disclosed for spatial resolution tip-enhanced Raman spectroscopy (TERS) imaging. The method includes physically separating a light excitation region from a Raman signal generation region on a remote-excitation tip-enhanced Raman spectroscopy (RE-TERS) probe. Also disclosed is a method of fabricating a remote-excitation tip-enhanced Raman spectroscopy (TERS) probe, and a system for spatial resolution tip-enhanced Raman spectroscopy (TERS) imaging.

  • Device integrated with scanning probe for optical nanofocusing and near-field optical imaging
    Patent number: 11054440
    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).
