Cactus Materials, Inc. patented eGaAs technology enables the company to build critical wavelength optical interconnects for scaling AI data centers faster and cheaper.

Cactus Materials, Inc. is an American semiconductor designer, developer, and manufacturer headquartered in Tempe, Arizona. Operating its own fabrication facility, the company develops Silicon Carbide (SiC) power semiconductors and advanced photonic devices that enable next-generation power and optical infrastructure. The company’s high-voltage (SiC) silicon carbide solutions improve the efficiency and performance of critical power systems serving energy, transportation, industrial, data center, and defense markets. Its photonic technologies including lasers, photodetectors, and optical components are based on Gallium Arsenide (GaAs) material systems and enable high-speed communications, artificial intelligence, sensing, and next-generation data center networks. The company also holds proprietary intellectual property in dilute nitride bandgap engineering, enabling extended-wavelength operation and reducing reliance on traditional Indium Phosphide (InP) substrates. This approach improves supply chain resilience while expanding product usability and integration flexibility across optical systems. By combining expertise in power electronics and photonics, Cactus Materials is positioned to support two major global trends: the electrification of critical infrastructure and the optical connectivity powering the AI economy.
