Schematic flow for optoelectronic parts selection

1. ABSTRACT  Photonic technologies have changed the world of communications in the form of fibre optics, integrated optics, electro-optical components and micro-photonics. They offer some compelling advantages compared with their traditional RF counterparts when considered for use in space applications. Therefore, research and development of photonics technologies for space applications in areas of communications, sensing and signal processing has been a major theme for several years.
The use of photonic technologies for space applications has risen the problem related to the ability of optoelectronic and optic components to withstand space environment as all optoelectronic and optic components come from terrestrial applications. Therefore, the development of photonic technologies for space applications has made the selection and acceptance test criteria of all optoelectronic and optic components that are part of the photonic system imperative.
The paper presents a summary of the experience of Alter Technology Group on the mechanical, thermal, radiation and endurance testing on several photonics technologies.  In addition the paper describes an assessment related to the reliability of these parts to be used in space applications together with the critical requirements to be considered for associated environmental testing.
