POET Technologies Collaborates with Yuanjie Semiconductor Technology for Laser Supply as the Company’s Optical Engines Enter Volume Production

October 10, 2023

Toronto, Ontario, October 10, 2023 -- POET Technologies Inc. (POETor the Company) (TSX Venture: PTK; NASDAQ: POET), the designer and developer of the POET Optical Interposerand Photonic Integrated Circuits (PICs) for the data center, telecommunication and artificial intelligence markets, today announced that it is collaborating with Yuanjie Semiconductor Technology Inc. (YST), a leading supplier of high-performance lasers. The collaboration will enable POETs joint venture, Super Photonics Xiamen (SPX), to ramp optical engines to high-volume production utilizing YSTs lasers.

“As we start ramping production of our optical engines, securing an additional reliable laser source that is well established in the industry with known good quality is of utmost importance to our business,” said Dr. Suresh Venkatesan, Chairman & CEO of POET. “Our partnership with YST has enabled POET and SPX to deliver reliable, high-performance optical engines to customers. SPX will start production of 100G CWDM4, POET ONEÔ (a 100G single chip TxRx engine), 100G LR4 and 200G FR4 optical engines using YST’s directly modulated lasers (DMLs) this month and we expect to extend the collaboration to other products in the future.”

“We are excited to collaborate with POET to support a growing customer demand for 100G and 200G optical engine products,” said Peter Zhang, CEO and Chairman of the Board at YST. “Our superior quality lasers and reputation for reliability will complement POET’s Optical Interposer technology, which offers a unique and highly adaptable platform to module makers. We will continue to collaborate with POET on high-speed optical engines while supporting SPX to ramp current products to high volume production.”

POET, SPX and YST will initially collaborate on 100G CWDM4, POET ONE, 100G LR4 and 200G FR4 transmitter products. All the design verifications and reliability testing of the optical engines is complete and all will be released to production this month.  Current module customers for these products include ADVA, Beijing FeiYunYi (BFYY) and Fibertop, along with others whose names have not yet been disclosed.
