24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Prior partnership,AI announcements have been positively framed but followed by negative 24h price reactions, suggesting a pattern of market skepticism toward collaboration news.
Over the past year, POET has repeatedly announced strategic partnership,AI deals. Collaborations with Sivers Semiconductors targeted scalable light‑engine subsystems with prototypes in H1 2026 and production readiness by end of 2026. A separate partnership with NTT Innovative Devices focused on a 100G bidirectional optical engine and highlighted growth forecasts for AI‑related networking markets. Despite these seemingly positive strategic steps, each of these partnership announcements was followed by a negative one‑day price reaction, framing today’s news within a history of cautious market responses.

SAN JOSE, Calif., March 17, 2026 (GLOBE NEWSWIRE) -- POET Technologies Inc. ("POET" or the "Company") (NASDAQ: POET), a leader in integrated photonics solutions for artificial intelligence networks, and Lessengers, a developer of advanced optical connectivity technologies, today announced the joint development of a 1.6T 2×DR4 optical transceiver module designed for next-generation AI clusters and hyperscale data center networks.
The effort combines POET’s highly integrated optical engines, built on its Optical Interposer™ platform, with Lessengers’ Direct Optical Wiring (DOW) technology, creating a scalable architecture for high-density optical interconnects required by emerging AI infrastructure. The 1.6T 2×DR4 transceiver will utilize POET’s optical engines to integrate lasers, modulators, photodiodes, and passive optical components on a compact photonic platform. Lessengers’ DOW technology provides a flexible optical wiring approach that enables efficient optical routing between photonic devices and fiber interfaces, helping simplify packaging while supporting high-bandwidth optical connectivity.
Samples of the 1.6T 2×DR4 transceiver module are targeted for availability in Q2 2026, aligning with the anticipated industry transition toward higher bandwidth optical links for AI-driven data center networks.
“AI infrastructure is driving rapid increases in optical bandwidth requirements,” said Raju Kankipati, POET’s Chief Revenue Officer. “By combining POET’s Optical Interposer-based optical engines with Lessengers’ innovative Direct Optical Wiring technology, we are developing an efficient path toward 1.6T 2×DR4 transceiver modules that can meet the performance, scalability, and integration requirements of next-generation data center architectures.”
“Lessengers’ Direct Optical Wiring (DOW) technology was developed to simplify optical connectivity while enabling scalable high-speed optical interconnects,” said Taeyong Kim, Chief Marketing Officer at Lessengers. “Integrating our DOW technology with POET’s Optical Interposer platform brings together complementary innovations that support the development of compact, high-performance 1.6T optical modules for hyperscale and AI networking environments.”
Both companies will showcase their technologies at the 2026 OFC Conference and Exhibition, taking place March 16–19 at the Los Angeles Convention Center.
Attendees are invited to visit:
- POET Technologies – Booth 339
- Lessengers – Booth 415
to learn more about the companies’ technologies and their work toward next-generation optical interconnect solutions.
The market forecast for 1.6T DR8 is more than 125 million units over the next five years (2027-2031), according to a LightCounting report. Both DR8 and 2xDR4 address the same market, with the only difference being the type of optical connector used.
