Microscopic “pen” enables direct-writing of light traps

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. 

This work has been published in the journal Advanced Materials  and has been featured in the inside front cover  of the same. It has also been highlighted by Optics and Photonics News , a publication of The Optical Society.
