Printed Droplets as Light Traps

What is it about?

Using ultra-high-resolution inkjet printing, this work demonstrates the possibility of trapping light at the nanoscale by 'writing' small ink droplets onto photonic crystals. The approach is reproducible, high-throughput, scalable, and applicable to a wide range of optoelectronics materials, thus bringing along a manifold of opportunities in sensing, lasers, biotechnology, and studying light-matter interaction.
