Biomimetics that imitates the functionality of nature becomes increasingly important as it can give rise to a sustainable solution to environmental and energy challenges but also provide a new technology platform for artificial innovations that do not exist in nature. Biomimetic photonics is inspired by nature’s ability to self-assemble complex nanostructured materials with superior optical properties to that of conventional materials. Artificial construction of bio-inspired photonic devices ultimately requires three-dimensional 3D printing with nanometre resolution. In this sense, super-resolution photoinduction-inhibition nanolithography (SPIN) is advantageous in developing bioinspired nanophotonic devices. It has been discovered that the circular birefringence in a 3D nanostructures inspired by butterfly wings (Callophrys rubi) can been revealed with a feature exceeding their natural origins. More intriguingly, these nano-engineered  nanostructures can support the topologic state of light if the parity symmetry is broken. These unprecedented 3D nanotechnology platforms allow for the accelerating development of biomimetic neural networks. Recently, it has been demonstrated that laser patterning is also a power tool for nanofabricating fractal micro-supercapacitors inspired by the internal structure of natural fern leaves (Polystichum munitum). We have also fabricated neuron-inspired Steiner tree structures using the three-dimensional direct laser fabrication method. An ultra-low density three-dimensional Steiner tree structure with the feature size of 1 µm is achieved.

Theme: Interferometry and Ophthalmic Optics

John E. Greivenkamp is a Professor at the Optical Sciences Center of the University of Arizona where he has taught courses in optical engineering since 1991.  After receiving a Ph.D. from the Optical Sciences Center in 1980, he was employed by Eastman Kodak.  He is a fellow of SPIE-the International Society for Optics and Photonics and of OSA. He serves as the editor for the SPIE Field Guides Series and is the author of Field Guide to Geometrical Optics.  He is the founder and curator of the Museum of Optics at the College of Optical Sciences.  Professor Greivenkamp was honored with the 2017 SPIE Educator Award and he serves as the 2019 SPIE President-Elect.

A long-term research program has been in place at the College of Optical Sciences to apply interferometry to ophthalmic applications. The first developed system is a transmission Mach-Zehnder interferometer that measures the transmitted wavefront of a contact lens while it is submersed in saline in order to determine the refractive power distribution of the lens. A second system makes use of a low-coherence interferometer to measure the index of refraction of contact lens materials. This system measures very thin samples that must remain hydrated in saline during the measurement. A third system also makes use of low-coherence interferometry to characterize the surface profile of both surfaces of a contact lens.   Combined with index information, a complete model of the contact lens can be produced. Two additional interferometers examine the dynamics of fluid layers on the surface of a contact lens (in vitro) and of the tear film on the surface of the cornea (in vivo). Both of these systems are instantaneous phase shifting Twyman-Green interferometers. The evolution and changes to the fluid surface is measured at video rates with sub-wavelength precision.

Machine learning is a powerful mathematical tool to explore relations and knowledge hidden in observation data. In the imaging field, superior performance of object recognition comparable to human perception is achieved by machine learning on deep neural networks. Not surprisingly, machine learning is also efficient for imaging applications other than simple object recognition. As the instances, object recognition and imaging were demonstrated with machine learning on the observation signals passing through scattering media, and flexible light control beyond scattering media was achieved by the same scheme. Another possibility of machine learning application is found in alternative implementation of well-established optical engineering. Holography generation and wavefront sensing can be achieved by deep learning. In this talk, potential capabilities and future directions of machine-learning applications in optical sensing and imaging will be presented.

Keywords:machine learning, deep neural network, scattering imaging, generated holography, wavefront sensing

Theme: First Direct Image of a Black Hole
Paul Ho
East Asian Observatory, Hawaii, USA

Paul was born in Hong Kong, and immigrated to the United States at the age of 11.  He received his training at MIT, obtaining both his S.B. (1972) and Ph.D. (1977) degrees in physics.  He served as postdoctoral fellow at the Five College Radio Astronomy Observatory, and at the Radio Astronomy Laboratory at UC Berkeley.  He was then faculty member at Harvard University before becoming SMA Project Scientist and Senior Astrophysicist at the Smithsonian Astrophysical Observatory.   He has served as ASIAA Director during 10 of the last 17 years in Taiwan.  He is currently the Director General of the East Asian Observatory.His scientific interests include molecular spectroscopy for resolving 3D dynamics , molecular outflows as the core process in star and planet formation, magnetic field via dust polarization morphology as the principal process in cloud collapse, supermassive black hole as the definitive probe of high gravitational fields, large surveys of galaxies as a window on early cosmological structures.  In his efforts to drive the growth of astronomy in Taiwan, Paul focuses on the development of instrumentation for forefront fields in astronomy.  These include the SMA, AMiBA, ALMA, GLT, TAOS, WIRCam, HSC, PFS, ERG, and SPICA.  Participation in these projects gained access for Taiwan to frontier research in astronomy, while building the infrastructures in Taiwan in terms of manpower, technology, and industrial partnership.  Paul has promoted the participation of Taiwan in the EACOA, which unites the East Asian Observatories to work on regional collaboration and development, in order to make Asia competitive with the western countries.  Paul has an H-index of 73. His most cited papers are on interstellar ammonia, the construction of the SMA, and the interacting M81 galaxy group as seen in HI.  Paul is an academician of the Academia Sinica, and a Fellow of The World Academy of Sciences.  

The Event Horizon Telescope, a network of 8 radio telescopes, operating at millimeter-wavelengths, and spanning the surface of the earth, has successfully produced the first picture of a black hole.  We achieved the highest angular resolution in astronomy by using the Very Long Baseline Interferometry.  This Supermassive Black Hole, in the nucleus of the M87 galaxy, is the first case where we can resolve the event horizon, where even light itself cannot escape from the gravity  of the black hole.  This first picture also demonstrates directly Einstein’s General Relativity on the distortion of space in the presence of strong gravity.  In addition, we detect the glow of material swirling around the black hole in the form of an accretion disk, where material gather before falling inside the black hole.  Asia has played a major role in this experiment.  More improvements are coming.
