Series B Fuels SemiNex Expansion into AI Data Center Photonics

SemiNex Corporation, a U.S. leader in high-power infrared semiconductor lasers and optical amplifiers, announced the successful completion of its Series B funding round. The investment will accelerate SemiNex’s strategic focus on next-generation data center infrastructure and the adoption of optical interconnects for AI, high-performance computing, and quantum applications.

Founded in 2003 and headquartered in Danvers, Massachusetts, SemiNex designs and manufactures proprietary indium phosphide (InP) laser diodes and semiconductor optical amplifiers (SOAs) that deliver industry-leading optical output power, thermal efficiency, and electrical performance. These technologies enable the replacement of traditional copper interconnects with high-bandwidth, low-latency optical solutions capable of meeting the exponential demands of AI workloads.

The Series B proceeds will fund the expansion of SemiNex’s cleanroom capabilities, including advanced automated testing and inspection equipment to produce “known good dies” at scale. This investment positions SemiNex to meet growing demand from hyperscale data center operators and technology leaders seeking optical solutions that drive energy efficiency, scalability, and long-term system performance. Leveraging a hybrid fab model, patented epitaxial material systems, and a flexible approach to custom solutions, SemiNex provides long-term OEM partnerships and market agility that few competitors can match.
