NTT Innovative Devices Corporation is a Japanese technology manufacturer within the NTT Group, specialising in advanced optical, electronic, and photonics devices for telecommunications, data centres, computing, sensing, and digital video applications. The company is particularly focused on combining photonics and electronics to increase data-transmission capacity while reducing size and power consumption. This work is closely connected with NTT's IOWN (Innovative Optical and Wireless Network) initiative, which aims to develop high-capacity, low-latency and energy-efficient communications and computing infrastructure.
The company's roots go back to 1982, when Nihon Denshi Gijutsu KK was established. It later became NTT Electronics Corporation and developed into a specialist supplier of optical communications technology. In August 2023, NTT Electronics merged with NTT Innovative Devices Corporation and adopted the NTT Innovative Devices name. The reorganised company brought together device development, design, manufacturing and sales, with a particular emphasis on photonics-electronics convergence. Its headquarters are in Yokohama, with facilities in Atsugi and Ibaraki and subsidiaries in the United States, Europe, Hong Kong and Shenzhen.
A major part of NTT Innovative Devices' business is optical communications. Its products include digital signal processors (DSPs), coherent optical transmitter and receiver components, semiconductor lasers, avalanche photodiodes, planar lightwave circuits (PLCs), optical switches, wavelength multiplexers and demultiplexers, and integrated silicon-photonics devices. These components are used in high-speed fibre-optic networks, Ethernet and passive optical networks (PON), metropolitan and long-haul communications, and connections between data centres.
One of its key technologies is photonics-electronics convergence (光電融合), in which optical and electronic functions are integrated more closely. The company's COSA coherent optical sub-assemblies, for example, combine silicon-photonics transmitter and receiver technology in compact packages, while its ExaLIGHT products integrate optical components with digital signal processing. Such devices are intended for 400 Gbps and other high-capacity networks, including data-centre interconnections. NTT Innovative Devices is also working towards optical chiplets and co-packaged optics that could bring optical connections much closer to processors and other computing hardware.
Beyond optical communications, the company develops high-speed transmission ICs and broadband network technology, photonic components for sensing, photonic network systems, Vision AI solutions, and digital video technology. Its background in video includes semiconductor devices and codec systems for broadcasting and telecommunications, with products used by broadcasters, telecommunications carriers, equipment manufacturers, local authorities and system integrators in Japan and overseas.
The website is primarily a technical and corporate resource rather than a consumer-oriented NTT site. It provides detailed product specifications and application information; technical material on optical communications and photonics; company history and corporate information; locations; environmental and procurement policies; and news and exhibition announcements. It is particularly useful for information on NTT's development of optical communications components, silicon photonics, coherent transmission, DSP technology and the hardware being developed to support future IOWN networks.
