PHOTONICS // III-V
High-performance lasers & detectors for the next generation of photonics
Cactus Materials’ Photonics Division develops and manufactures advanced optoelectronic semiconductor devices for high-speed optical communications, sensing, aerospace, defense, and industrial photonics — built on proprietary eGaAs™ dilute-nitride technology.
PHOTONICS TECHNOLOGY
Extending GaAs into InP wavelengths
Our Photonics Division builds on proprietary eGaAs™ (Engineered Gallium Arsenide) dilute-nitride technology to extend mature GaAs manufacturing into the wavelength ranges traditionally served by more expensive indium-phosphide (InP).
For decades InP has powered the 1310 nm and 1550 nm windows of modern fiber optics — at higher cost, lower volume and a more complex supply chain. Dilute-nitride lets GaAs reach those wavelengths while keeping the cost, maturity and scalability of established GaAs fabrication.
02 — The platform
Precisely engineered bandgaps
The eGaAs™ platform combines advanced materials engineering with precision epitaxial growth to create highly engineered semiconductor structures whose bandgap can be precisely tailored for specific applications. Quantum efficiency measurements demonstrate exceptional bandgap tunability across a broad wavelength range — allowing us to optimize device performance across 850 nm to 1600 nm while maintaining excellent optical efficiency and reliability.
03 — How we differentiate

04 — The opportunity
Delivering the future of long-wavelength photonics
AI, cloud computing, hyperscale data centers, advanced sensing and secure communications are driving unprecedented demand for optical components that combine speed, reliability, manufacturability and affordability.
By enabling high performance in the 1310 nm and 1550 nm bands on a mature GaAs platform, Cactus offers a compelling alternative to InP — lower manufacturing cost, higher production scalability, vertically integrated domestic manufacturing, and exceptional device performance.
