报告题目：Complex Optical Fields: Recent Advances and Future Perspectives
摘要：Driven by their potential applications, complex optical fields with spatially tailored amplitude, phase and polarization within the cross section have drawn significant attention recently. In this talk I will review some of the latest development of this rapidly growing field of optics and offer a general overview of the current status of this field in a few areas. Particularly a time-reversal methodology for the creation of a wide variety of exotic optical focal fields with prescribed characteristics within the focal volume will be presented. Recently developed methods for the generation of complex optical fields that utilize a vectorial optical field generator, fiber lasers, and metasurfaces are summarized. I will also present the interactions of these complex optical fields with various micro- and nano- structures and discuss their perspective applications.
