There are well-known advantages to using these photonic technologies in space, such as the limited generation of noise, electromagnetic immunity,
Fabrication technology and packaging strategy for 300V-5A Silicon Carbide Schottky diodes with a wide temperature operation range capability (between -170ºC and 300ºC). These diodes have been designed for harsh environment space applications such as inner Solar System exploration probes.
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.
After expose key elements on the evaluation of Optoelectronic Components for Space Applications, where thermal vacuum and other environmental restrictions such temperature range, radiation or vibration and examples of Optoelectronic characterizati0ons done in our laboratories, we have been provided that Alter Technology is the world´s leader in engineering, testing and procurement of High Reliability Electronic Components
