The generalization of deep neural network algorithms to a broader population is an important challenge in the medical field. We aimed to apply self-supervised learning using masked autoencoders (MAEs) to improve the performance of the 12-lead electro

All-optical logic elements containing nonlinear material
Autor: Shinnosuke Sawa, Tetsuro Yabu, Kazuhiro Nishida, Masahiro Geshiro
Publikováno v: Electronics and Communications in Japan (Part II: Electronics). 85:1-12
For a highly information-oriented society, further enhancement of the capacity and speed of communications and information systems is necessary. For this purpose, all-optical logic elements are expected as a promising solution. In this paper, structu

A dual-plane comb-line filter having plural attenuation poles
Autor: Toshiaki Kitamura, Yasushi Horii, Shinnosuke Sawa, Masahiro Geshiro
Publikováno v: IEEE Transactions on Microwave Theory and Techniques. 50:1216-1219
In this paper, a dual-plane comb-line filter having plural attenuation poles is proposed. We investigate the filtering characteristics from both experiments and numerical simulations by means of the finite-difference time-domain method. It is shown t

All-optical logic gates containing a two-mode nonlinear waveguide
Autor: Toshiaki Kitamura, Tetsuro Yabu, Masahiro Geshiro, Shinnosuke Sawa, K. Nishida
Publikováno v: IEEE Journal of Quantum Electronics. 38:37-46
We propose a new element containing a two-mode nonlinear waveguide consisting of Kerr-like material for all-optical logic circuits. The proposed element, incorporated into the Mach-Zehnder interferometer, functions like a phase shifter. Although the

A proposal of a WDM transmission system using three wavelength bands of 1.3, 1.47, and 1.55?m employing optical amplifers
Autor: Shigeyuki Seikai, Ikuo Yamashita, Shinnosuke Sawa
Publikováno v: Electrical Engineering in Japan. 135:43-51
A WDM transmission system using the wavelength bands of 1.3, 1.47, and 1.55 μm is proposed. Selection of these wavelengths makes it possible to use off-the-shelf optical couplers and to apply known types of amplifiers. Among three kinds of optical a

Symmetric three-branch optical power divider with a coupling cap
Autor: Shinnosuke Sawa, N. Minimi, Masahiro Geshiro, Tetsuro Yabu
Publikováno v: Journal of Lightwave Technology. 17:1693-1699
Proposed is a new fork-type three-branch optical power divider consisting of two different dielectric materials. The structure is composed of a symmetric Y-branch waveguide with a phase front retarder and a center branch located a coupling gap apart.
