One-step casting techniques will yield PMMA rods with arrays of internal channels which can be empty, or filled with different clear polymer. Polymer microstructured optical fibre (PMOF) suitable for high bandwidth communications is then produced by drawing. It is urgently needed for local communication networks in cars and buildings. Solid PMOF channels are new to this project, and should make PMOF easier to deploy. Nanoscale mapping of light transport modes and polymer defects will help validate channel designs.Read moreRead less
Photoactive Semiconducting Biopolymers. The basic aims of this project are to elucidate, manipulate, and utilise the unique chemical and physical properties of a class of biopolymers called the melanins. These materials are the only known solid state semiconducting biopolymers, and are non-toxic, biocompatible, and biodegradable. Their use as active components in biomimetic soft electonic, optoelectronic or photovoltaic devices, has not hitherto been demonstrated.
