Radiation sensitivity of GaAs components is not really well known, compare to other technologies. Traditional radiation harness policy consisted in a good derating in DC bias conditions to ensure operation inside a known or expected DC safe operating area (SOA). However...
High brightness semiconductor lasers are potential transmitters for future space lidar systems. In the framework of the European Project BRITESPACE, we propose anHigh Brightness Semiconductor Lasers allsemiconductor laser source for an Integrated Path Differential Absorption...
Spacecraft structural health-monitoring applications are pushed forward by increased constraints in the cost of launching payloads into orbit that dictates major reduction in structural weight only attained through the use of advanced materials and innovative manufacturing...
A novel integrated optical source capable of emitting faint pulses with different polarization states and with different intensity levels at 100 MHz has been developed. The source relies on a single laser diode followed by four semiconductor amplifiers and thin film polarizers...
In space applications, optocouplers may need to work at very low temperatures. Under this low temperature operating conditions, the device degradation subjected to radiation exposure may show different behaviour compared to a standard radiation test under room temperature. The...
The efficient generation of photon pairs requires very strict characteristics on the illuminating beam, such e.g. its size, shape, and polarization state. For these photon pairs to be entangled in their polarizations there must be a superposition of two distinct pair-generation...
This article describes the setup developments and some of the results obtained for the temperature characterization from -190ºC to more than +300ºC of passive components normally used for space missions, but with a standard operating temperature range in most of the cases. One...
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...
ASER diodes are increasingly used for space applications, either to pump solid state lasers, in photonic payloads, or as sources for LIDAR or spectrometric applications. In space applications reliability issues are a primary concern and among them, radiation hardness is one of...
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...
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...
