Wooriro Begins Full-Scale Commercialization of Photodetectors for AI Data Centers

200Gbps Photodetector Prototype Performance Validated

Aiming for Market Launch in September

Wooriro, a domestic company specializing in optical communication and quantum communication semiconductors, has completed validation of its photodetector technology.

Wooriro announced that it has completed in-house prototype development and performance validation based on the 200Gbps-class photodetector technology transferred from the Electronics and Telecommunications Research Institute (ETRI). The company stated that it has officially begun the commercialization process, aiming to enter the market in September 2026.

A photodetector (PD) is a key semiconductor device that converts optical signals transmitted through optical fiber into electrical signals. It is an essential component of optical transceivers used in artificial intelligence (AI) data centers, cloud networks, and 5G·6G communication networks.

Following the technology transfer from ETRI, Wooriro has focused on optimizing device design and internalizing manufacturing processes. Through prototype validation, the company maximized optical coupling efficiency by applying ETRI's backside lens (BacksideLens) integration structure technology, and designed the device to ensure stable reception characteristics even in ultra-high-speed data transmission environments.

Han Youngtak, Ph.D. at ETRI, who led the technology transfer, said, "Achieving 200Gbps photodetector device performance in a short period of time was possible thanks to Wooriro's outstanding process technology," adding, "This is expected to become a representative success case of technology commercialization by combining original research institute technologies with corporate manufacturing capabilities."

A Wooriro official stated, "The 200Gbps photodetector chip is a core optical semiconductor technology for leading the AI data center era," and added, "With the recent prototype achieving the optical performance required by customers, we have firmly established the potential for actual commercialization." The official continued, "We are smoothly proceeding with customer evaluations and mass production preparations, aiming for an official entry in September 2026. Furthermore, we plan to expand our lineup to 400Gbps-class photodetectors and secure competitiveness in the global optical semiconductor market for AI data centers."
