Silicon photonics for space optics technologies
Space is a new but inevitable frontier for Silicon Photonics technologies. The “New Space economy” has drastically lowered satellite launch costs such that constellations of communications satellites have become a reality, and small satellites for imaging, environmental monitoring, and global positioning are proliferating. The surge in satellite traffic will demand a corresponding surge in satellite data communications capacity.Satellite based free-space optical (FSO) communications links will come online over the next few years to complement existing radio frequency links, to enhance the bandwidth, power efficiency, and security of satellite communications. All of the “Prime” aerospace contractors are in the process of demonstrating initial FSO systems, using fibre and bulk optics components. Low size, weight, and power consumption are critical for all space technologies, and especially for small satellite payloads. With Silicon Photonics whole optical systems or subsystems can be integrated onto single chips, giving huge advantages in each of these metrics, and giving resilience to vibrations.
