Microscopic “pen” enables direct-writing of light traps
Oct 24, 2017
A team of researchers jointly lead by Prof. Vincenzo Pecunia and Dr. Frederic Brossard has established a new paradigm in hybrid nanophotonics: the realisation of nanophotonic devices through the direct-writing of functional inks on conventional inorganic photonic crystal templates.
Key to this breakthrough has been the adoption of electrohydrodynamic-jet printing, which serves as a microscopic “pen” that allows the jetting of functional inks in the form of tiny droplets (feature size of ~ 1 μm). The significance and appeal of this paradigm closely relate to the benefits of inkjet printing, which brings along simplicity, on-demand local deposition, and high throughput.
This newly-established paradigm has considerable potential for easy-to-fabricate nanophotonics for sensing applications (e.g., to detect tiny amounts of biomolecules such as viruses or cancer cells), for the study of strong light-matter interaction in new functional materials, and for the creation of highly compact optical circuits.
