Exploring a direct printing technique for polymeric optical interconnects and modulators

Direct printing technique has become indispensable in flexible electronics and low cost sensor applications. It has transformed into an enabling technology for many flexible devices. However, it is not very well explored for printing optical materials. In this work, a micro-dispense printer for printing polymeric optical waveguides was custom-built. It was employed to develop a simple method to couple light into printed optical interconnects. It was also used to apply a voltage bias during printing and drying of electro-optic polymer (SEO110) to pole the SEO110 in-situ with the goal of eliminating the need for traditional high temperature contact poling. With this in-situ poling method, electro-optic effect in SEO110 was demonstrated.
