POET Technologies and Quantum Computing Inc. announced a collaboration to co-develop 3.2Tbps optical engines using thin-film lithium niobate modulators for next-generation AI and data center networks, with completion targeted for 2026.

POET Technologies Inc and Quantum Computing Inc. announced a strategic collaboration to co-develop 3.2Tbps optical engines for co-packaged optics and next-generation AI connectivity, according to a press release.

The collaboration will combine Quantum Computing Inc.’s expertise in thin-film lithium niobate (TFLN) modulators with POET’s Optical Interposer platform. The resulting 400G-per-lane modulator-based engine aims to deliver high-speed data transfer for AI systems and hyperscale data centers.

Under the agreement, POET will fund the development of the 400G/Lane modulator, with completion targeted for the second half of 2026. The companies stated that the TFLN-based components will enable twice the speed of current networking devices while supporting wafer-level manufacturing.

The global market for 3.2T connectivity solutions in pluggable and co-packaged optics formats is projected to approach $12 billion by 2030, according to the release.
