Title: Arbitrary vector spatiotemporal beamshaping: simultaneous control of amplitude, phase and polarization at any delay
Abstract: We present a new class of beam shaper, capable of generating arbitrary vector spatiotemporal beams, where we can define the amplitude, phase, and polarization independently for each point in space and time. This device was recently used to showcase time reversed optical waves. Such waves propagate through complex photonics media, from a seemingly random-like ‘pre-scattered’ wave, which then becomes the desired target field after propagation through the complex media. Such device opens new opportunities for the study of complex light-matter interactions, optical communications and imaging in depth through complex materials.
About the Speaker: Dr. Mickael Mounaix is an Australian Research Council Discovery Early Career Researcher Award (ARC DECRA) Research Fellow at the University of Queensland in Brisbane, Australia. He has research interests in the field of light manipulation and pulse shaping in complex materials such as multimode optical fibers or multiple scattering media. He completed his PhD in 2017 under the supervision of Prof Sylvain Gigan at Sorbonne University, where he investigated how to control ultrashort pulses of light in scattering media. In 2018, he joined Dr. Joel Carpenter’s group at the University of Queensland to study the shaping of light in multimode optical fibers. In 2021, he was awarded an ARC DECRA fellowship to investigate further development of the simultaneous shaping of all the properties of light (spatial, temporal/spectral and polarization).
