Rotational varifocal moiré metalens made of single‐crystal silicon meta‐atoms for visible wavelengths

Chikara Ogawa, Sotaro Nakamura, T. Aso, Satoshi Ikezawa et autres

Abstract Metasurface lenses (metalenses) offer an ultrathin and simple optical system with dynamic functions that include focal length tuning. In this study, a rotational varifocal (i.e., moiré) metalens based on octagonal single‐crystal silicon pillars was designed and fabricated to realize a high …

A remark on uniform Strichartz estimate for quantum walks on 1D lattice

T. Aso, Masaya Maeda

In this short note, we study quantum walks (QWs) on one dimensional lattice $\delta \mathbb{Z}$. Following Hong-Yang, we prove Strichartz estimates for QWs independent of the lattice width $\delta$.

Level-1 silicon vertex detector trigger at Belle

H. Kurashiro, H. Aihara, Y. Asano, T. Aso et autres

We present a newly developed fast trigger system that uses the silicon vertex detector (SVD) for the Belle experiment at the KEKB energy-asymmetric e/sup +/e/sup -/ collider. It is designed to issue the trigger with a latency of 1.85 /spl mu/s for …

Measurement of interstrip and coupling capacitances of silicon microstrip detectors

E. Barberis, N. Cartiglia, David Hutchinson, J. R. Leslie et autres

The authors present a set of measurements of the capacitances on silicon microstrip detectors which are important for the operation of the detectors. Various strip widths on both the junction and the ohmic side and widths of blocking p+ implant on the …
