A P2P-based Communication Framework for Geo-Location Oriented Networks
Autor: Takumi Miyoshi, Yusuke Shimomura, Olivier Fourmaux
Publikováno v: Journal of Telecommunications and Information Technology, Iss 1 (2019)
This paper proposes a novel peer-to-peer communication framework to implement geographical location oriented networks, called G-LocON. Location-based services have been gaining in popularity, as proven by ridesharing and mobile games. Although these

Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
A single multicore-fiber bidirectional spatial channel network that efficiently accommodates asymmetric traffic is proposed and demonstrated using a core-selective-switch-based spatial cross-connect with an M × N wavelength-selective switch and a bi

Birefringent atomic vapor laser lock in a hollow cathode lamp
Autor: Yusuke Hayakawa, Yoshio Torii, Takumi Sato, Yusuke Shimomura, Takatoshi Aoki, Naohiro Okamoto
We report a robust method of stabilizing a laser to the frequency of an atomic transition using a hollow cathode lamp. In contrast to the standard dichroic atomic vapor laser lock method, which uses dichroism induced by a longitudinal magnetic field,
