Unlocking the cosmos: leveraging deep space communication

The rapid expansion of Earth observation has led to an abundance of high-definition data that needs to be transferred back to Earth. Traditionally, satellites have relied on radio frequencies (RF) for their communication links with Earth, but these systems suffer from inherent bandwidth limitations, making them less capable of handling the increasing data volumes. Laser communications, which rely on the propagation of light in free space, offer significant benefits over RF systems.

Enabling high-speed data transfer with laser communication

The ultra-high-speed capabilities of laser communications will enable the transmission of more data from space. Optical communications are inherently free from spectrum limitations, avoiding interference with other signals and the need for operating licenses. Resistant to jamming, laser communication ensures reliable data transmission even in contested environments. To ensure sufficient link availability, a large number of optical ground stations (OGS) is required.

Waveguide-integrated SNSPDs for even higher data transmission rates

SNSPDs enhance the performance of the OGS receiver subsystems that must operate during the day and deal with the laser signal attenuated by atmospheric conditions.

Our waveguide integrated SNSPDs meet this need for high detection efficiency in the telecom band, low dark count rates and high maximum count rate.

Faster, better, further

By combining the advantages of laser communication with the superior performance of WI-SNSPDs, space communications can achieve unprecedented levels of data transfer efficiency, security, and reliability, unlocking new possibilities for space exploration and advanced applications.

The development of optical communications between satellites and ground stations can achieve throughput in the Tbps range and ensure seamless integration with existing terrestrial networks. This could enable almost unlimited connectivity for advanced applications such as 5G/6G and space-based internet.
