“Spatial mode manipulation in communications and imaging”.


The ability to analyse and control light’s spatial properties is a fundamental requirement in many disciplines throughout optical physics. Imaging is an obvious example, where how light occupies space is measured directly to reveal details of the object being imaged. However other applications such as telecommunications and the field of Space Division Multiplexing are also increasingly looking to the spatial properties of light as a means of increasing information capacity.

In this talk, research will be presented on measuring and manipulating light’s spatial properties. This includes the creation of ‘pre-scattered’ light states which can propagate through a scattering media, only to form a desired image on the other side. As well as work on the creation of devices capable of splitting a light beam up into the spatial modes it is composed of, a functionality for the spatial domain that is analogous to how a dispersive prism splits white light up into its constituent colours.


Joel Carpenter received his PhD in Electrical Engineering from the University of Cambridge, UK in 2012 for his work on Mode Division Multiplexing in optical telecommunications before working as a postdoctoral researcher at The University of Sydney, Australia. He is now a Lecturer at his alma mater, The University of Queensland. His research focuses on the measurement and manipulation of fiber modes using spatial light modulators and computational holography.
