The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has successfully developed a highly efficient optical modulator using the organic electro-optic polymer (hereinafter referred to as EO polymer) for visible light. Conventional EO polymer optical modulators could operate in near-infrared light (wavelength 1,550 nm, etc.), but they couldn’t be used for visible light (wavelength 380 nm to 780 nm) because of the large absorption loss at visible light. NICT has developed an EO polymer which has small absorption loss in visible light and a large electro-optic coefficient required for the optical modulator. We fabricated an optical modulator using this EO polymer by microfabrication technology and operated the optical modulator in visible light (red, wavelength 640 nm). The demonstrated optical modulator for visible light is smaller and more efficient than the conventional EO polymer optical modulator for near-infrared light.more
The National Institute of Information and Communications Technology (NICT, president: TOKUDA Hideyuki, Ph.D.) is the first in the world to generate standard time referenced to an optical clock. By adjusting the time interval (the effective duration of the second) to match that generated by an intermittently operated optical lattice clock, the difference between the time generated at NICT and Coordinated Universal Time (UTC) is reduced to less than five billionth of a second. This is less than a quarter of the previous difference, which could reach up to 20 billionth of a second.more
Japan Radio Co., Ltd. (Representative Director and President: Takeshi Koarai, hereinafter JRC), SKY Perfect JSAT Corporation (President & Chief Executive Officer: Eiichi Yonekura, hereinafter SKY Perfect JSAT), and the National Institute of Information and Communications Technology (President: Hideyuki Tokuda, Ph.D., hereinafter NICT) jointly worked to conduct a Japan-Europe joint experiment for connecting satellite and 5G, including Japan-Europe long-distance network. Successful transmission of 5G control-plane signal, 4K video, and IoT data was achieved in January and February of 2022 for the first time in Japan. This experiment was conducted in collaboration with the University of Tokyo, School of Engineering, Nakao Research Laboratory, the European Space Agency (ESA), Eurescom GmbH, and Fraunhofer FOKUS Institute. This joint experiment shows that 5G communications can be established over long-distance links between Japan and Europe, including satellite links, and be expected to lead to the early spread of 5G networks in places where 5G deployment has been difficult, such as in the sky, at sea, or on remote islands.more
Researchers from the Network Research Institute at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) report the world's first demonstration of more than 1 petabit per second in a multi-core fiber (MCF) with a standard diameter of 0.125 mm. The researchers, led by Benjamin J. Puttnam, constructed a transmission system that supports a record optical bandwidth exceeding 20 THz by exploiting wavelength division multiplexing (WDM) technology.more
The National Institute of Information and Communications Technology (NICT) (President: TOKUDA Hideyuki, Ph.D.) and the Financial Services Agency of Japan (JFSA) worked together to develop a new AI-based translation engine that can translate documents between Japanese and English in both directions with high accuracy. The JFSA has collected, and provided to the NICT, a large number of translation documents owned by the JFSA and financial industry groups. The NICT has refined them into data suitable for deep learning to develop the high-precision AI-based engine.more
In March 2022, National University Corporation Tokai National Higher Education and Research System, Nagoya University (President: MATSUO Seiichi) provided approximately 530,000 Japanese-English translation sentences consisting of university regulations, notifications, and correspondences, to the National Institute of Information and Communications Technology (President: TOKUDA Hideyuki; hereinafter “NICT”), a National Research and Development Agency. The data will be used to help improve the accuracy of machine translation engines developed under the “Hon’yaku (Translation) Bank” scheme run by NICT and the Ministry of Internal Affairs and Communications.more

Quantum Innovation 2021 (The International Symposium on Quantum Science, Technology and Innovation) will be held as a virtual conference from Tuesday, December 7th, through Thursday, December 9th.
The aim of this symposium is to introduce quantum information processing technology and its trends in practical applications through guest speeches and technical sessions of each field. We expect to share a common view on the current study status including implementation results both in Japan and abroad as well as to promote international collaborations through the meetings with key persons from each country. We look forward to your participation.

A study group consisting of the University of Electro-Communications (UEC), National Institute of Information and Communications Technology (NICT), Meiji University, National Institute of Polar Research (NIPR), and Kyushu University has devised a method to observe noctilucent clouds (NLCs) appearing at 80-85 km altitude by focusing on the rim of the Earth captured in the disk images from the geostationary meteorological satellite Himawari 8. The group has established a real-time NLCs monitoring system using the satellite data. With the new monitoring method of NLCs or “Climate Canary”, contributions to studies related to climate changes including global warming are expected.more
