Abstract
Recent innovations in fiberoptic communications have developed a need for improved optical switching between cables. Current optical switches are expensive and challenging to manufacture. This thesis focuses on the design and creation of a liquid crystal waveguide using photolithography to allow for inexpensive and simple switching devices that can be integrated directly into fiberoptic networks. Liquid crystal (E7) acts as the guides within a polymer matrix (NOA 65). The theory and parameters of this experiment are described, as well as the fabrication and characterization of the liquid crystal waveguides. Results show that stable waveguides can be made using 35-40% liquid crystal E7 with 60-75% polymer NOA 65 at 90 C and 20 Watt UV light.
