报告摘要:

Metaphotonics is a new frontier which deals with manipulation of electric and magnetic fields and their coupling in nanoengineered materials, such as metamaterials and metasurfaces, to control the field distribution and propagation of electromagnetic waves. One of our main activities in Metaphotonics focuses on chiral media which intrinsically couple electric and magnetic dipoles. These media allow for chirality control of linear and nonlinear optical processes, opening new directions for optical signal processing, beam manipulation and sensing. We have developed new generation chiral polymers with large linear and nonlinear optical chiralities, and demonstrated new phenomena of plasmonic and excitonic enhancement in their nanocomposites with metallic nanoparticles or quantum dots, aimed towards producing a new class of metamaterials. A new direction is interaction of complex light (with orbital angular momentum) with a complex medium (chiral). We have shown manipulation of magneto-optic effect in nanocomposites of chiral polymers with magnetic nanoinclusions which can lead to a new generation of highly sensitive magneto-optic material that are capable of sensing weak magnetic field due to brain waves.

 

报告人简介:

PARAS N. PRASAD, Ph.D., is SUNY Distinguished Professor of Chemistry, Physics, Electrical Engineering and Medicine; Samuel P. Capen Chair of Chemistry; and Executive Director of the Institute for Lasers, Photonics and Biophotonics. In 2005, Scientific American named him among the top 50 science and technology leaders in the world.  He has published more than 750 scientific papers, along with four field-defining monographs in Nonlinear Optics, Biophotonics, Nanophotonics, and Nanomedicine; eight edited books; and numerous patents. He has received the Morley Medal and the Schoellkopf Medal from the American Chemical Society; a Guggenheim Fellowship, a Sloan Fellowship; the Western New York Health Care Industries Technology/Discovery Award; a SUNY Excellence in the Pursuit of Knowledge award; UB’s first Innovation Impact award; and his University’s President’s Medal. Prasad is also the winner of SPIE’s highest honor of President’s Gold medal, Optical Society of America’s Michael Feld Biophotonics award and IEEE’s Pioneer Award in Nanotechnology in recognition of his numerous pioneering contributions to nanophotonics, biophotonics and nanomedicine. He is a fellow of the APS, OSA, and SPIE, and a senior member of IEEE. He is on the Thompson Reuters “Highly Cited Researchers” list for 2014 and 2016. Prasad has received Honorary Doctorates from KTH in Sweden, the Aix-Marseille University in France and MEPhI in Russia.

Beyond his outstanding scholastic and research achievements, his work has had substantial technological and societal impact. His technologies have produced nine spin-off companies, one of which, a publically traded company, Nanobiotix, is now in advanced clinical trial for cancer therapy. Prasad has also mentored many students and championed young faculty members across the globe.
