Fig. 1 Design and fabrication of a wafer-scale organic printed photonic chip. Design and fabrication of a wafer-scale organic printed photonic chip. (A) Schematic of the fabrication of a photonic circuit by confining photon flows in printed structures. A thin film was spin-coated from a polymer solution and locally dissolved by printing solvent droplets, resulting in various microscale structures for light transport. (B) Image of a free-standing photonic chip peeled off from the substrate, indicating the flexibility and transparency of the printed photonic chip. A yellow-dye compound was doped into the chip film. (C) Image of large-scale ordered optical structures on a 1-inch wafer. (D) Microscope image showing printed microring chains of uniform size and well-defined pattern. (E) AFM image of a typical self-assembled polymer structure after printing showing the smoothness and height of the structure over the surrounding film. Chuang Zhang et al.
