Optical Waveguide Modelling, Measurement and Design for Optical Printed Circuit Board

• Waveguides were lithographically made of Truemode® polymer • The refractive index of core was 1.556 and cladding was 1.5264 gives NA = 0.302 • Lithographic process was optimised for 50 μm thick waveguides • Waveguides measured were 50 μm thick unless otherwise stated • Different manufacturing technologies: photolithography, laser-writing, laser ablation, extrusion, and inkjet printing will be characterised later in this project.
