About us
【Name】 Seiji Nishiwaki
【Adress】 optics@wsems.tech
【Career】 Graduated from the Faculty of Engineering at the University of Tokyo in 1980 and joined Matsushita Electric (now Panasonic). I retired in 2020. Doctor of Engineering.
【Areas of Expertise and Achievements】 Optics and Scientific Computing. The papers published in the last 10 years are as follows.
(1) Efficient colour splitters for high pixel-density image sensors (Received
the Optical Design Award in 2013)
(2) Interference phase-contrast imaging technology without beam separation (Received
the Optical Design Award in 2019)
(3) Efficient light-trapping sheet for the entire visible spectrum by using stacked concentric grating couplers
(4) Biaxial 360-degree scanning LIDAR using a liquid crystal control
【Background of the creation of this work】 All calculating simulators for electromagnetic fields have their advantages and disadvantages, and I felt for many years whether there is anything that I could do. Moreover, commercially available products cost millions of yen in maintenance costs alone. After retirement, I wondered if I could create a comprehensive simulator that could be used by individuals, and created this work by making full use of the knowledge of optics and programming that I had cultivated. It has the meaning of supplementing my enjoyment of manufacturing when I was working.
