Dr. Wataru Nakagawa, Assoc. Prof. of Electrical & Computer Eng., presents his sabbatical seminar

NANOPHOTONICS APPLICATIONS AND SABBATICAL EXPLORATION

Abstract
Dr. Nakagawa will highlight a few examples of interesting work in nanophotonics that I encountered on my sabbatical adventures during 2018–2019. One key example is the application of interference microscopy to characterize the features of a microfabricated diffractive optical element. Although some a priori knowledge of the sample is necessary, we demonstrate that phase-resolved imaging of the sample enables measurement of feature widths and lateral displacement of the sample with resolution exceeding the diffraction limit. He will also summarize examples of interesting work he saw that might form the basis for future research collaboration.

Biography
Wataru Nakagawa is an Associate Professor in the Department of Electrical and Computer Engineering at MSU. He received the Ph.D. degree in Electrical and Computer Engineering (Applied Physics) from the University of California, San Diego, under the mentorship of Prof. Shaya Fainman. His current research interests include nanophotonics, optical metamaterials, polarization optics based on nanostructures, and interdisciplinary applications for such devices and nanostructures. Wataru has lived on three different continents, enjoys visiting both familiar and new places, and is anxiously awaiting the day when travel becomes possible again.
