NTT and three partners have been selected for a NEDO-backed project to develop mass-production methods for optical chiplets, devices that move data between processors using light instead of electricity. NTT announced the selection on 20 October 2026 in an [official release](https://group.ntt/en/newsrelease/2026/10/20/261020a.html).

## Key Details at a Glance

| Company | Role |
| --- | --- |
| NTT Innovative Devices | Project lead; manufacturing, testing and packaging for mass production |
| Japan Semiconductor | Silicon photonics mass-production technology |
| Furukawa Electric | Compound semiconductor-based optical devices |
| Shinko Electric Industries | Optical chiplet packaging and in-process inspection |
| NTT, Inc. | Advisor; supply chain development |

## What an optical chiplet does

An optical chiplet pairs a photonic integrated circuit with an electronic one through high-density packaging. It sends data between processors such as CPUs and GPUs using light, which aims to reduce power use and increase bandwidth in AI servers and data centres.

## The project goals

The aim is more than a tenfold increase in manufacturing productivity compared with current R&D-stage processes. The partners will also establish and evaluate a pilot production line designed for future commercial manufacturing, under NEDO’s programme for advanced semiconductor manufacturing technologies.

Japan Semiconductor is a wholly owned subsidiary of Toshiba Electronic Devices & Storage Corporation. NTT has led optical chiplet packaging R&D under the NEDO programme since fiscal year 2023.

## Reported figures

Posts citing Nikkei and Nikkan Kogyo mention a line in Iwate, about Y24 billion in cost with NEDO funding about Y16 billion, and targets of 100,000 units a year by 2031 and 1 million by 2033, with samples from 2028. NTT’s own release does not state these figures, so treat them as press reports.

## What Is Not Confirmed

- The funding split, Iwate location, volume targets and 2028 sample date come from Nikkei reports relayed on social media, not from NTT’s release.

## Quick Answers

### Who leads the project?

NTT Innovative Devices.

### What is the productivity goal?

More than tenfold.

### Why optical chiplets?

To cut power use and boost bandwidth in AI servers.
