- Significant increase achieved with combination of cutting-edge technologies -

Researchers from the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), in collaboration with the Eindhoven University of Technology and University of L’Aquila demonstrated a record-breaking data-rate of 22.9 petabits per second using only a single optical fiber, which was more than double our previous world record of 10.66 petabits per second.

- High-performance photon detection with superconducting strips over 200 times wider than conventional nanostrip -

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) invented a novel structure in a superconducting strip photon detector*1 that enables highly efficient photon detection even with a wide strip, and succeeded in developing the world's first “Superconducting Wide-Strip Photon Detector (SWSPD)”.

– Available for computational simulations such as electromagnetic absorption in children –

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has developed computational human body models for children aged 1, 5, and 10 years whose body shape and anatomical structure match international references. These models are available free of charge for non-commercial use and are useful for diverse simulations, such as studying electromagnetic field dosimetry and human body injuries in car accidents and enhancing diagnostic and therapeutic practices. They are expected to aid in child safety assessments and advancements in various fields.

– Available for accurate simulation of human exposure to radio waves over 20 GHz –

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) released an open-source database of tissue dielectric properties on March 30, 2023. This database was constructed using the datasets of 58 types of tissue in the frequency range from 1 MHz to 100 GHz. This database includes many of the novel measurement data particularly those obtained above 20 GHz, which include operating frequency bands of 5G systems.

Researchers invented a novel method to measure the permittivity of insulators 100 times more accurately than before. This technology is expected to contribute to the efficient development of sensitive radio receivers for radio telescopes as well as to the development of devices for the next generation communication networks, “Beyond 5G/6G.”

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), Sumitomo Osaka Cement Co., Ltd. (President: MOROHASHI Hirotsune), Nagoya Institute of Technology (President: Dr. KINOSHITA Takatoshi), and Waseda University (President: TANAKA Aiji, Ph.D.) jointly developed the world's first system for the transparent relay, routing, and switching of high-speed terahertz-wave signals to different locations. Direct conversion of a 32-Gb/s terahertz-wave signal in the 285-GHz band to an optical fiber and its transparent relay and switching to different access points in ultrashort time periods were successfully demonstrated.

Expectations for next-generation mobile communications based on photonic technology

・Wireless electronics that have been used thus far in next-generation mobile communications using terahertz waves may reach their technical limit (namely, upper limit of frequency for wireless electronics).
・Terahertz wireless communication in the 560-GHz band was achieved by optical-to-electrical conversion of ultra-high-frequency photonic RF signals in near-infrared micro-resonator soliton comb.
・Adding the low-phase noise that is characteristic of micro-resonator soliton comb to terahertz waves makes it possible to achieve ultra-high-speed and large-capacity wireless communication using advanced modulation and demodulation of amplitude and phase.

Tokyo, March 24, 2023 - A consortium of joint research partners including RIKEN, the National Institute of Advanced Industrial Science and Technology (AIST), the National Institute of Information and Communications Technology (NICT), Osaka University, Fujitsu Limited (Fujitsu) and Nippon Telegraph and Telephone Corporation (NTT) announced the successful development of Japan’s first superconducting(1) quantum computer(2). Starting March 27, 2023, the partners will provide the newly developed technology to users in Japan as a cloud service for non-incommercial use under a joint research agreement with RIKEN.

- Key technology for long-distance optical communication after Beyond 5G -

A group of researchers from the National Institute of Information and Communications Technology (NICT, Japan) and Sumitomo Electric Industries, Ltd. (SEI, Japan) in collaboration with the Eindhoven University of Technology, University of L’Aquila, and Macquarie University has developed a 19-core optical fiber with a standard cladding diameter (0.125 mm), which has the largest number of cores among the standard cladding diameter multi-core fibers, and has demonstrated large-capacity transmission at a data-rate of 1.7 petabits per second over a distance of 63.5 km. A randomly coupled multi-core fiber design was used to achieve high core density, as well as a multiple input multiple output (MIMO) digital signal processing to eliminate inter-core signal interference.
