Since the start of 2026, global laser and optoelectronics giants have been riding a wave of “stepping up their bets on China.”

On June 15, global materials giant Corning signed a project to establish a new company in Jiading, Shanghai, targeting a world-leading optical interconnect manufacturing base with an annual output value of around $1 billion.

This is far from an isolated case. In the first half of 2026 alone, besides U.S.-based Corning, laser and optoelectronics heavyweights such as Germany’s Zeiss and Japan’s Hamamatsu Photonics have also landed major investment projects in quick succession. From the Yangtze River Delta and the Guangdong-Hong Kong-Macao Greater Bay Area to the Beijing-Tianjin-Hebei region, they are making dense moves and continuously expanding their presence.

Why are these century-old optical powerhouses unanimously placing big bets on China? What exactly are they after?

Corning Chases Light: Jiading base Lands in Shanghai

On June 15, Corning officially signed an agreement with Shanghai's Jiading District. The U.S. company will lease more than 14,000 square meters of factory space at the Haoyuan Intelligent Manufacturing Industrial Park in Loudian Town (Jiading Industrial Zone), with a planned investment of RMB 200 million to build a large-scale production base for high-precision fiber optic connector assemblies. The goal: a world-leading optical interconnect manufacturing base with an annual output value of approximately $1 billion. 

Why is Corning raising its bet at this particular moment? The answer lies in AI computing power. Optical interconnect, in simple terms, replaces copper cables with optical fiber to transmit data between servers in data centers, offering higher bandwidth, lower latency, and lower energy consumption. Training large AI models requires thousands of GPUs working in parallel, making high-density, low-latency optical interconnect products a "must-have" for computing infrastructure.

In an interview with Xinhua Finance, Lin Chunmei, President and General Manager of Corning Greater China, put it bluntly: the optical communications business is benefiting from the incremental demand driven by artificial intelligence.

The numbers tell the same story. In the first quarter of 2026, Corning reported core sales of $4.35 billion, up 18% year over year. Within that, the optical communications business posted revenue of $1.85 billion, surging 36% year over year, while net profit soared 93% to $387 million. 

Corning's "China chess game" extends far beyond Jiading. The company has already built a complete localized industrial chain in China: optical fiber preforms in Haikou, optical fiber in Caohejing, and connectivity solutions in Jiading.

Expanding production in the U.S. while doubling down in China, Corning's "two-front strategy" shows exactly why China is not only a vital market but also an irreplaceable manufacturing and innovation hub in the global AI optical interconnect landscape.

ZEISS Doubles Down on China: Twin Bets in Waigaoqiao and Guangzhou

While Corning is chasing light with a bet on AI computing power, German optics giant ZEISS is doubling down on China on a broader scale, marking two highlight moments in the first half of 2026.

On February 7, 2026, ZEISS officially broke ground on its Greater China headquarters complex in the Waigaoqiao Free Trade Zone in Pudong. The campus spans more than 50,000 square meters of planned construction land with a total investment of approximately RMB 1.2 billion, making it ZEISS's largest single infrastructure investment in its nearly 70 years in China.

Two months later, on April 21, the ZEISS Optics Town was inaugurated in Huangpu District, Guangzhou. The city has designated more than 300 mu (about 20 hectares) of industrial development land for the project, focusing on high-end optical manufacturing and the R&D and production of AR/VR devices and core components.

With one move in the north and one in the south, ZEISS is firing on both fronts. The company's confidence stems from the weight of the Chinese market—in 2021, China surpassed the United States and Germany for the first time to become ZEISS's largest single market worldwide. Over the past decade, ZEISS's revenue in China has grown sixfold.

Notably, ZEISS's strategic focus is shifting from a "manufacturing base" to a "source of innovation." The ZEISS China Customer Experience Center, unveiled in September 2025, is the company's only customer experience center worldwide that integrates technological resources from all business units. The new Waigaoqiao campus will combine R&D, management, customer experience, and high-end manufacturing to create an "open and shared innovation cooperation platform."

In frontier fields such as AI + optical inspection and precision medicine, ZEISS is deeply embedding itself into China's industrial ecosystem. The head of ZEISS Greater China said the company is not only introducing high-end technologies but also deeply investing in local R&D and innovation, ensuring that its technologies and products take root in local application scenarios.

Hamamatsu Deepens China Presence: Langfang Phase III Completed

The Japanese optoelectronics giant is also accelerating. On January 17, the completion ceremony for the Phase III project of the Langfang branch of Beijing Hamamatsu Photon Techniques Co., Ltd. was held.

This modern optoelectronic industrial base, with a total investment of several hundred million yuan and built over 488 days, was officially put into operation. It includes three main buildings—a crystal building, a module building, and a warehouse—with a total floor area exceeding 30,000 square meters. once fully operational, it is expected to add annual sales of 100 million yuan.

Hamamatsu's ties with China's optoelectronics industry date back to 1988, when the company entered the Chinese market with photomultiplier tube technology. Over the past 37 years, Hamamatsu has completed a full transformation from a "technology importer" to a "local innovator," with products widely used in key fields such as nuclear medicine, space exploration, and oil well logging.

According to reports, the Langfang base is the core hub of Hamamatsu's China operations. Phase I was completed and put into production in 2005, Phase II in 2015, and Phase III was completed in January 2026. This "Langfang base trilogy" is a microcosm of Japanese optoelectronics companies' deep cultivation of the Chinese market.

Hamamatsu Photonics has positioned Phase III as a "systematic upgrade carrier for the innovation ecosystem," anchored in three directions: releasing new production capacity, tackling core "bottleneck" optoelectronic technologies, and driving the development of regional industrial clusters.

Currently, Hamamatsu Photonics has completed the full transformation from "technology importer" to "local innovator" in China. Its products are widely used in key fields such as nuclear medicine, space exploration, and oil well logging, and the company has become a "little giant" enterprise in the field of optoelectronic materials.
