3D printing of plasmonic nanofocusing tip enabling high resolution, high throughput and high contrast optical near-field imaging
Abstract Scanning near-field optical microscopy (SNOM) offers a means to reach a fine spatial resolution down to ~ 10 nm, but unfortunately suffers from low transmission efficiency of optical signal. Here we present design and 3D printing of a fiber-bound polymer-core/gold-shell spiral-grating conic...
