Craft Prospect Initiates PERSEUS: Advancing European Optical Satcom

Strategic Integration

Glasgow-based Craft Prospect has officially launched the PERSEUS project, a collaborative initiative aimed at redefining high-performance optical communications for the space sector. According to SpaceNews, the firm is partnering with the Fraunhofer Centre for Applied Photonics (CAP) and Vector Photonics to explore advanced laser architectures designed for satellite environments.

The PCSEL Advantage

Central to the PERSEUS mission is the integration of Photonic Crystal Surface Emitting Lasers (PCSELs). Unlike traditional edge-emitting or vertical-cavity lasers, PCSELs offer a unique combination of high power, single-mode operation, and low divergence. This hardware transition is critical for overcoming current limitations in inter-satellite links and space-to-ground data transmission, where thermal management and beam quality remain primary bottlenecks.

Operational Goals

The project seeks to mature the technology for integration into small satellite platforms. By leveraging Fraunhofer’s expertise in photonics systems and Vector Photonics’ proprietary laser designs, Craft Prospect aims to establish a robust European supply chain for optical terminals. The shift toward optical frequencies is mandated by the increasing data demands of Earth observation and telecommunication constellations, which have outpaced traditional RF spectrum capacity.

Terminal Readiness

PERSEUS represents a tactical move to secure sovereign capability in quantum-secure communications and high-bandwidth networking. The project will focus on characterizing laser performance under space-simulated conditions, ensuring that PCSEL technology can withstand the radiation and thermal cycles inherent to low Earth orbit (LEO).
