Eindhoven, Tuesday, 9 June 2026.
Japanese advanced materials maker Dexerials has launched a joint research program with the Netherlands’ Photonic Integration Technology Centre, targeting technology that merges light and electronics on a single chip — a potential breakthrough in reducing the soaring energy costs driven by AI-powered data centers.

A Deal Announced on June 8, 2026

On June 8, 2026, Dexerials Corporation — headquartered at 1724 Shimotsubayama, Shimotsuke-shi, Tochigi, Japan, and led by Representative Director and President Yoshihisa Shinya — formally announced the initiation of joint research in the field of photonics with the Photonic Integration Technology Centre (PITC), a photonics research and development institute based in the Netherlands [1][5]. The announcement was filed as a timely disclosure on the Tokyo Stock Exchange on the same date, under Dexerials’ listed ticker code 4980 [5]. The collaboration operates under a research program led by the Netherlands Organisation for Applied Scientific Research (TNO), combining Dexerials’ expertise in functional materials and optical semiconductors with PITC’s advanced R&D infrastructure [1][6][7].

What This Is — and Why It Matters

This partnership sits squarely within the field of photonics — specifically, the subfield of photonic integrated circuits (PICs) and optoelectronic integration, which merges optical and electronic components onto a single chip [1][3]. To understand why that matters, consider the scale of the energy problem it is designed to address: the rapid proliferation of generative AI has driven a dramatic increase in global data center power consumption, and this surge has become a recognized crisis in the technology sector [1][3][6][7][8]. Co-Packaged Optics (CPO), one of the flagship technologies targeted by this collaboration, is a next-generation approach that physically integrates optical transceivers with switching silicon, replacing power-hungry electrical interconnects with light-based ones [2][3]. In plain terms, instead of sending data between chips using electricity — which generates heat and wastes energy — CPO uses photons, which travel faster, dissipate less heat, and enable far greater data throughput at a fraction of the energy cost [GPT]. Dexerials itself defines the broader technology category — called photoelectronic fusion, or optoelectronic integration — as a next-generation technology that fuses electrical and optical signals to achieve high-speed, energy-efficient communication and information processing, and notes that its application in data centers is already advancing incrementally [1][3][6].

The Institutions Behind the Research

PITC was founded as an open R&D center specifically to accelerate the industrial application of photonic integrated circuits [1][3][6][7]. Its founding consortium brings together four major Dutch institutions: Eindhoven University of Technology (TU/e), the University of Twente (UT), TNO, and PhotonDelta [1][3][6][7][8]. This collaborative, pre-competitive structure — where competing companies and academic institutions pool resources before any single organization claims proprietary advantage — is a deliberate design choice, intended to accelerate knowledge transfer and push photonics technologies from the laboratory toward commercial production [3][6]. TNO, the overarching research body coordinating the joint program with Dexerials, was established in 1932 by an Act of the Dutch Parliament as an independent applied research organization, and is described as the largest applied research institution in the Netherlands and one of the foremost in Europe [6][7]. PhotonDelta, another PITC founder, publicly congratulated both Dexerials and PITC on the launch of the collaboration on June 8, 2026, highlighting the role such partnerships play in strengthening the global photonics ecosystem amid rising demand for energy-efficient data infrastructure [2].

Dexerials’ Strategic Position and Dutch Footprint

Dexerials Corporation was established on June 20, 2012, and describes itself as a functional materials manufacturer engaged in the development, production, and sale of electronic components, bonding materials, and optical materials, with group companies also active in the development and manufacture of photonics products including optical semiconductors [6][7]. The company has explicitly designated the photonics domain — including optical semiconductors — as a growth driver under its Mid-term Management Plan 2028, titled ‘Achieving Evolution,’ which spans fiscal years 2024 through 2028 [1][3][6][7]. Crucially, Dexerials had already established a meaningful physical presence in the Netherlands well before this announcement. Its European subsidiary, Dexerials Europe B.V., operates marketing bases in both the Netherlands and Germany, and additionally maintains a satellite office at High Tech Campus Eindhoven, located in the province of North Brabant in the Netherlands — an open-innovation hub where companies, universities, and research institutions collaborate to accelerate technology development and commercialization [1][3][6][7]. That existing infrastructure made the PITC partnership a logical next step, rather than a cold approach from afar.

A Broader Japan–Netherlands Photonics Axis Takes Shape

The Dexerials–PITC deal does not exist in isolation. On June 9, 2026 — the same day this article is published — the Brabant Innovation Day (BID) Tokyo 2026 is taking place at The Okura Tokyo, located at 2-10-4 Toranomon, Minato-ku, Tokyo, from 11:30 to 19:45 [4]. The event, organized by the Province of North Brabant in partnership with the Brabant Development Agency (BOM), the Netherlands Foreign Investment Agency (NFIA), and the Netherlands Embassy in Tokyo, has already reached maximum registration capacity [4]. PITC is represented at the event by R&D Scientist Takeshi Kamijo and Senior Business Development Manager Jan Tatousek, while confirmed speakers also include PhotonDelta CEO Eelko Brinkhoff and Johan Feenstra, CEO of SMART Photonics [4]. Dexerials itself participated in an earlier Dutch-Japanese semiconductor and photonics program alongside Hitachi High Tech, contributing insights on strategic partnerships and manufacturing collaboration within the Dutch high-tech ecosystem [4]. The Dutch Embassy in Tokyo’s Counsellor for Innovation, Eras Draaijers, has outlined a strategic deeptech collaboration agenda between the Netherlands and Japan scheduled to run through 2026 and 2027, signaling that the Dexerials–PITC announcement is part of a deliberate, government-backed effort to deepen bilateral technology ties in semiconductors and photonics [4].

What Comes Next

Under the Mid-term Management Plan 2028, Dexerials has committed to accelerating its research, development, and production capabilities specifically in the photonics and optical semiconductor domains, with CPO and related optoelectronic fusion technologies as primary targets [1][3][6][7][8]. The joint research with PITC is structured to combine Dexerials’ material science and optical semiconductor strengths with PITC’s foundational R&D capabilities, aiming to build a stronger technology base in photonics in anticipation of continued market expansion [1][2][3][6][7][8]. For the broader photonics industry, the partnership represents a concrete step toward closing the gap between laboratory-stage photonic integration and commercially deployable products — a transition that Takeshi Kamijo of PITC and TNO specifically presented on at the Brabant Innovation Day earlier in 2026 under the theme ‘From Lab to Fab’ [4]. Whether this collaboration accelerates the timeline for CPO deployment at industrial scale remains to be seen [alert! ‘No specific commercial deployment timelines or milestones have been disclosed in the available sources’], but the institutional backing — spanning a Japanese advanced materials manufacturer, a Dutch applied research consortium, two Dutch universities, and a government-aligned innovation accelerator — suggests this is a well-resourced and strategically serious undertaking [1][2][3][4][6][7][8].
