1. Naoya Tate, Tadashi Kawazoe, Wataru Nomura, Motoichi Ohtsu, Shunsuke Nakashima, Development of Zinc Oxide Spatial Light Modulator for High-Yield Speckle Modulation, IEICE Transactions on Electronics, 10.1587/transele.E99.C.1264, E99-C, 11, 1264-1270, 2016.11, In order to realize high-yield speckle modulation, we developed a novel spatial light modulator using zinc oxide single crystal doped with nitrogen ions. The distribution of dopants was optimized to induce characteristic optical functions by applying an annealing method developed by us. The device is driven by a current in the in-plane direction, which induces magnetic fields. These fields strongly interact with the doped material, and the spatial distribution of the refractive index is correspondingly modulated via external control. Using this device, we experimentally demonstrated speckle modulation, and we discuss the quantitative superiority of our approach..
2. Naoya Tate, Makoto Naruse, Tsutomu Matsumoto, Morihisa Hoga, Yasuyuki Ohyagi, Shumpei Nishio, Wataru Nomura, Motoichi Ohtsu, Non-scanning optical near-field microscopy for nanophotonic security, Applied Physics A: Materials Science & Processing, 121, 4, 1383-1387, 2015.07, We propose a novel method for observing and utilizing nanometrically fluctuating signals due to optical near-field interactions between a probe and target in near-field optical microscopy. Based on a hierarchical structure of the interactions, it is possible to obtain signals that represent two-dimensional spatial patterns without requiring any scanning process. Such signals reveal individual features of each target, and these features, when appropriately extracted and defined, can be used in security applications—an approach that we call nanophotonic security. As an experimental demonstration, output signals due to interactions between a SiO2 probe and Al nanorods were observed by using near-field optical microscopy at a single readout point, and these signals were quantitatively evaluated using an algorithm that we developed for extracting and defining features that can be used for security applications..
