Resonant laser processing for fabrication of nanobiophotonic devices

Functional nanophotonic devices realized by the state-ofthe-art nanofabrication technologies have offered the control of light with nanoscale precision, which are boomingly used in advanced bio-sensors and bio-imaging systems. Most of the functional nanophotonic devices rely on the ability to precisely control its individual metaelements within the subwavelength scale. The absorption in metallic or dielectric elements provides a new route for photo-to-thermal conversions and processing. Here, we introduce a resonant laser processing (RLP) technique as a flexible photo-thermal post-writing technology for masscustomization of optical devices.
