A New Hardware Layer for Free Space Optical Satcom

---

A pioneering microwave-photonics-based hardware that complements digital optical links and enables small relay satellites, multi-orbit connectivity, and sustainable network expansion. This new hardware layer bridges the gap between RF and optical domains, unlocking a path toward compact, scalable, and energy-efficient space communication systems.

Our solution is up to 100× smaller than traditional payload systems used in core satellites, leading to dramatically lower manufacturing, integration, and launch costs. This miniaturization enables affordable access to space connectivity for emerging satellite operators and research missions.

Designed for a longer lifetime (>5 years) with minimal maintenance needs, our hardware has a low impact on space observation and contributes to reducing space debris footprint. By supporting hardware reuse and component longevity, we promote sustainable growth in orbital infrastructure.

Network expansion is achieved by replicating low-cost, sustainable small relay satellites, allowing rapid and flexible coverage growth. This modular approach enables operators to scale capacity dynamically across multiple orbits without complex redesigns or major capital increases.

Operating across the wide spectrum available at THz frequencies, our system is adaptable to both existing and emerging standards. Its frequency-agnostic microwave-photonics foundation ensures compatibility with next-generation space communication protocols and intersatellite link topologies.

A simplified, standardized design enables cross-vendor compatibility, significantly reducing integration costs and eliminating repeated in-lab testing cycles. This openness accelerates deployment and supports a healthy, competitive satellite ecosystem.

Our approach minimizes the need for complex digital signal processing and high-power RF front-ends, improving efficiency and reliability. More coverage is achieved thanks to our optical-microwave hybrid approach, which allows the realization of small relay satellites for dense and resilient satellite mesh networks.
