Fabrication of arrays of channel waveguides by self‐assembly using patterned organic monolayers as templates

Complex arrays of channel waveguides can be easily fabricated by the new approach reported here, which is based on microcontact printing and self‐assembly of solid, three‐dimensional polymeric structures from liquid precursors. It shows that structures produced by the procedure described act as multi‐mode optical waveguides, and suggestions are made for improvements following on from this demonstration of principle. Waveguides are important in communications, photonic sensors, and optical devices.
