POET Technologies and LITEON Announce Joint Development of Optical Modules for AI Applications

SAN JOSE, Calif., March 16, 2026 (GLOBE NEWSWIRE) -- POET Technologies Inc. ("POET" or the "Company") (NASDAQ: POET), a leader in the design and implementation of highly-integrated optical engines and light sources for artificial intelligence networks, today announced a strategic collaboration with LITEON Technology, one of the world’s leading providers of optoelectronic semiconductor components and high-power optical systems. The partnership aims to co-develop next-generation optical communication modules built on POET’s patented optical interposer technology and integration platform.

The jointly developed optical engine will leverage the POET Optical Interposer™ to integrate several optical components, drive electronics, and coupling structures into a compact, thermally optimized module. This approach enables scalable, cost-efficient production of advanced optical modules for next-generation co-packaged optics, AI systems, and high-bandwidth data center applications.

“LITEON has long been at the forefront of optoelectronic semiconductor innovation, delivering solutions spanning optoelectronics to high-power AI and HPC infrastructure,” said Sander Su, General Manager of the Optoelectronic Products Solutions Business at LITEON Technology. “By partnering with POET, our capabilities are extended into advanced photonic solutions that will enable the next generation of high-performance connectivity. Together, we aim to provide high-end laser solutions tailored for AI-driven data centers. We look forward to combining our respective manufacturing expertise and technological strengths to deliver exceptional value to customers worldwide.”

“This collaboration with LITEON is a major step forward in advancing optical connectivity for next-generation architectures,” said Dr. Suresh Venkatesan, Chairman & CEO of POET Technologies. “LITEON’s leadership in optoelectronics and precision manufacturing perfectly complements POET’s integration platform. Together, we are positioned to deliver highly scalable, power-efficient solutions that address the rapidly accelerating needs of AI and hyperscale data center customers.”

POET will begin development work this year and expects to have prototypes ready by late 2026. High-volume production is anticipated for 2027. POET is scheduled to attend the 2026 OFC Conference and Exhibition (March 16-19 at the Los Angeles Convention Center) and its representatives will be available for discussions on its products and business development. The Company’s booth at the show is No. 339.
