Semiconductor lasers (or laser diodes) operating in the wavelength region of 1.8 µm to 3 µm are attractive light sources for applications including remote sensing, laser spectroscopy or pollutant detection. Highly strained InGaAs Quantum Wells (QW) grown on InP substrates can...
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...
This paper describes the activities and results of an ESA-funded project concerned with the assessment of optical amplifier technologies and products for applications in fiber optic subsystems of future satellite payloads. On-board applications are briefly introduced, together...
A dedicated evaluation and qualification campaign has been performed on several optical COTS components in order to use them on ESA’s SMOS mission. The evaluation phase consisted of a set of critical tests and analyses and led to the selection of the flight lot component. After...
