In this paper, we will describe the work carried out within the framework of the evaluation of the reliability of pump combiners under space environment. This work includes the definition of the optical and environmental specifications.

Recent advances on radiation-hardened optical fiber technologies

Optical Fiber Communication and Exhibition (OFC) – March 2020

Silica-based optical fibers possess key advantages for integration in radiation-rich environments as parts of laser sources, optical amplifiers, etc. We reviewed how the understanding of the basic mechanisms of radiation effects can be exploited to optimize their tolerance.

Recent advances in radiation-hardened fiber-based technologies for space applications

Journal of Optics – 1 August 2018

Review of the recent progress on radiation-hardened fiber-based technologies, focusing on examples for space applications. We introduce the operational principles of the various fiber-based technologies considered for use in radiation environments.

Radiation influence on er and er/yb doped fiber amplifiers performances: high power and wdm architectures

Photonics West – January 2018

The actual challenge for space researchers is to increase the free space telecommunications data speed transfer. One of the most promising solutions is the optical communication systems. This technology can be used for the inter-satellite and/or satellite-ground links.

Robustness of astrix fiber optic gyros in space radiative environment

10th International ESA Conferenceon Guidance, Navigation & Control systems – June 2017

Development of radiation resistant passive and doped fibers started 10 years ago at iXblue. With tens of satellites flying using iXblue Optical Fibers, we now have access to data from real space environment – not only lab irradiation testing.

Optimized radiation-hardened Erbium Doped Fiber amplifiers for long space missions

Journal of Applied Physics 121, 163104 – 2017

In this work, we developed and exploited simulation tools to optimize the performances of rare earth doped fiber amplifiers (REDFAs) for space missions. To describe these systems, a state-of-the-art model based on the rate equations.
