Learn about the role that optical filters play in enabling these extraterrestrial photonics applications.
Background
“Space, the final frontier”. Over the past two decades optical filters established their value as the key wavelength selective elements in many terrestrial photonics applications from telecom to 3D cinema. As the capabilities of space-based photonics systems were expanding, the cost per kg to launch satellites was decreasing by orders of magnitude. These factors created a space race and drove rapid growth in two space-based applications utilizing these capabilities, Satcom and Earth Observation (EO). These systems became commercially viable to launch constellations of satellites into Low Earth Orbit (LEO).
EO satellites now provide daily optical images of every place on earth. This enables remote monitoring, measuring, and management in areas such as disaster response, agriculture, and the environment. Constellations of satellites are beginning to be deployed in LEO for Satcom. This lays the “ground work” for low latency, high throughput, and secure internet access to remote and rural communities around the world.
Optical filters provide the EO satellites with the ability to discriminate between different phenomena of interest, such as spectral identification of crop types and health. Most of the Satcom constellations being deployed require optical filters to optimize signal to noise and separate out optical signals as part of the optical intersatellite links (OISL) architecture that connects the web of satellites.
This webinar will discuss these applications and the optical filters that enable them along with key characteristics of the filters and challenges in their manufacture.
