Topic: Innovations Abound in Functional Optical Communications
Abstract:Optical communication systems have achieved great success over the past several decades in terms of capacity growth and deployment. Looking into the future, optical communications continues to innovate, with advances in functionality, reconfigurability, integratability, and stability. This presentation will highlight recent innovations and future potential of high-capacity and highly functional systems that may make use of optical signal processing, being a broadly defined term.

Topic: Light in a Twist: Optical Angular Momentum
Abstract:In 1992 Allen et al. recognized that light beams carrying an orbital angular momentum, in addition to the photon spin, could be created in the laboratory. This twist can be generated using lenses, or holograms encoded onto liquid crystal displays. Both whole beams and single photons can carry this twist, or transfer it to particles causing them to spin. In this talk I will introduce the underlying properties and discuss a number of manifestations of orbital angular momentum. These various demonstrations by our own group and others highlight how optics still contains surprises and opportunities for micro-manipulation, novel imaging modalities and high bandwidth communication in both the classical and quantum worlds. Our most recent work considers how a rotational form of the classical Doppler effect might by used to sense the rotation of distant bodies, even when the linear effect is zero.
Biography:Miles Padgett holds the Kelvin Chair of Natural Philosophy at the University of Glasgow. He leads QuantIC, a quantum imaging centre and one of four Quantum Technology hubs in the UK. In 2001 he was elected a Fellow of the Royal Society of Edinburgh (RSE) and in 2014 a Fellow of the Royal Society, the UK's National Academy. In 2009, with Les Allen, he won the Institute of Physics Young Medal, in 2014 the RSE Kelvin Medal and in 2015 the Science of Light Prize from the European Physical Society.

Topic: Photoacoustic Tomography: Ultrasonically Beating Optical Diffusion and Diffraction
Biograph: Lihong Wangearnedhis Ph.D. degree at Rice University, Houston, Texas under the tutelage of Robert Curl, Richard Smalley, and Frank Tittel. He currently holds the Gene K. Beare Distinguished Professorship of Biomedical Engineeringat Washington University in St. Louis. His book entitled “Biomedical Optics: Principles and Imaging,” one of the first textbooks in the field, won the 2010 Joseph W. Goodman Book Writing Award. He also edited the first book on photoacoustic tomography and coauthored a book on polarization. He has published 450peer-reviewed articles in journals, including Nature (Cover story), Science, PNAS, and PRL, and has delivered 440 keynote, plenary, or invited talks. His Google Scholar h-index and citations have reached 104 and 43,000, respectively. Hislaboratory was the first to report functional photoacoustic tomography, 3D photoacoustic microscopy (PAM), photoacoustic endoscopy, photoacoustic reporter gene imaging, the photoacoustic Doppler effect, the universal photoacoustic reconstruction algorithm, microwave-induced thermoacoustic tomography, ultrasound-modulated optical tomography, time-reversed ultrasonically encoded (TRUE) optical focusing, nonlinear photoacoustic wavefront shaping (PAWS), compressed ultrafast photography (100 billion frames/s), Mueller-matrix optical coherence tomography,and optical coherence computed tomography. In particular, PAM broke through the long-standing diffusion limit on the penetration of optical microscopy and reached super-depths for noninvasive biochemical, functional, and molecular imaging in living tissue at high resolution. Dr. Wang has received 37 research grants as principal investigator,with a cumulative budget of over $47M. Heisa Fellow of the AIMBE,Electromagnetics Academy,IEEE, OSA, and SPIE. He is the Editor-in-Chief of the Journal of Biomedical Optics. He chairs the annual conference on Photons plus Ultrasound, and was a chartered member of an NIH Study Section. Wang serves as the founding chair of the scientific advisory boardsoftwo companies which have commercialized photoacoustics. He received the NIH’s FIRST, NSF’s CAREER, NIH Director’s Pioneer, and NIH Director’s Transformative Research awards. He also received the OSA C.E.K. Mees Medal, IEEE Technical Achievement Award, IEEE Biomedical Engineering Award, SPIE Britton Chance Biomedical Optics Award, and Senior Prize of theInternational Photoacoustic and Photothermal Association for “seminal contributions to photoacoustic tomography and Monte Carlo modeling of photon transport in biological tissues.” An honorary doctorate was conferred on him by Lund University, Sweden. His lab is transitioning to Caltech.
