Spatially structured light involves the ability to tailor light to any desired profile, and has traditionally been done in amplitude and phase. More recently it has been possible to tailor complex vectorial light fields in the laboratory, opening up a range of exciting applications from fundamental physics to optical communication. In this talk I will cover the recent progress in creating, manipulating and detecting vectorial structured light. In the process I will discuss the exciting possibilities that this opens, from free space and fibre communication to hybrid entanglement for probing fundamental physical processes.
Andrew received his PhD (1998) from the University of Natal (South Africa), and subsequently spent several years working as an applied laser physicist, first for the South African Atomic Energy Corporation and then later in a private laser company. In 2004 he joined the CSIR National Laser Centre where he was Chief Researcher and Research Group Leader of the Mathematical Optics group. In March 2015 Andrew joined the U. Witwatersrand as a Distinguished Professor and has established a new laboratory for Structured Light. Andrew chairs or serves on the committees of several international conferences, OSA and SPIE committees, and serves on the editorial boards of Optics Express and J. Optics. He is active in promoting photonics and popularising science, a founding member of the Photonics Initiative of South Africa, a Fellow of both SPIE and the OSA, and an elected member of the Academy of Science of South Africa. He has published 200 journal papers and has won several awards nationally and internationally.
