Abstract

The direct interfacing of photonic crystal fiber to metallic nanoantenna has widespread application in nano-scale imaging, optical lithography, nanoscale lasers, quantum communication, in-vivo sensing and medical surgery. I will present the design, fabrication, and characterization of fiber-plasmonic probes for nanoscale chemical imaging. The proposed Fiber-based Tip-Enhanced Raman Spectroscopy (F-TERS) combines the spatial (<1 nm) and chemical resolution of TERS with the ease of use of Scanning Near-field Optical Microscopy. F-TERS can operate in virtually any gaseous and liquid environment, enabling new avenues of nanoscale chemical data collection from any sample analysis in most real-world environments.
