Laser processing for large area polymer photonic applications

Abstract
In the last years polymer photonics experienced a tremendous boost in research efforts, targeting for applications in short-reach optical interconnects, biosensing, medical diagnostics, multi-axial strain sensing, datastorage, etc. Polymers are relatively inexpensive, can be functionalized to achieve required optical, electronic, or mechanical properties, and have demonstrated compatibility with various patterning methods. We highlight our recent research efforts, challenges, and opportunities in the development of novel laser processes for defining complex polymer photonic components or structures, and how to integrate them into a common polymer platform. Laser direct write lithography has been selected as a promising approach for large area polymer optical waveguide definition. Experimental results are presented for a number of commercially available polymers, both for multi-mode and single mode waveguides. In- and outcoupling is provided by 45 degree micro-mirrors, which are defined by UV-laser ablation. Hybrid integration of laser and photodiode chips is provided by a low temperature flip-chip assembly process, enabled by laser-induced forward-printing for high-accuracy deposition of solder or conductive adhesives. Integration of pixelated organic LEDs onto the polymer platform is studied, for which a layer selective laser patterning process is investigated, using conventional nano-, and picosecond pulsed lasers in the visible and near-IR, together with novel lasers targetting for resonant mid-IR ablation.
