“…This manuscript describes a miniaturized EDFA developed and qualified for space operation, with a form factor compatible with the CubeSat platform. The optical power to size ratio is the biggest in the scientific literature and the satellite market to the best of the authors' knowledge [10] [11], meaning that this is the world's smallest space-qualified high-power optical amplifier. NICT plans to test it in orbit as a key component of the Cu-beSOTA mission, currently in preparation [5].…”

The Japanese National Institute of Information and Communications Technology (NICT) is currently developing a high-performance laser-communication terminal for CubeSats aimed at providing a high-datarate communication solution for LEO satellites requiring transmission of large volumes of data from orbit. A key aspect of the communication system is a high-power optical amplifier capable of providing enough gain to the transmitted signals to be able to close the link on its counterpart’s receiver with the smallest impact in terms of energy and power on the CubeSat’s platform. This manuscript describes the development of a miniaturized 2-W space-grade 2-stage erbium-doped fiber amplifier (EDFA) compatible with the CubeSat form factor, showing the best power-to-size ratio for a space-qualified EDFA to the best of the authors’ knowledge. Performance results under realistic conditions as well as full space qualification and test are presented, proving that this module can support short-duration LEO-ground downlinks as well as long-duration intersatellite links.

“…Select COTS components are used across the outline designs, leveraging G&H's heritage in hi-reliability and space-grade photonic products 2 . With the exception of the digital and analogue electronics, all other COTS components employed have undergone environmental testing to understand their suitability for space environments [3][4][5][6][7] .…”

“…Miniaturizing designs necessitates an increase in density, owing to the smaller volume. Most assemblies for pathfindertype missions have densities between 0.8 -1.1 g/cm 3 . The designs outlined here all have densities > 1.3 g/cm3, with the SmallCat and Perseus HP having a density of ≈ 1.6 g/cm 3 (Table 1) -highlighting the highly compact nature of the designs.…”

We present recent progress in developing miniaturized optical transmitters and receiver amplifiers for space communications. Three C-band high-speed optical transmitter designs are presented: a bespoke 300 mW version as part of TNO's "SmallCat" terminal to fly on-board NordSat and two variants that provide 300 mW and 3 W of optical power complying to standard cubesat form factors. In addition to these transmitters, an ultra-small form factor, high gain, low noise amplifier, for boosting received signals is presented.
