The Total Ionizing Dose (TID) radiation test on EEE parts involves a number of variables and processes which must be kept under control to ensure correct test execution and compliance with the used test method. From the test plan definition to the test report issue, proper... Continue reading
Given a general introduction on testing optical materials for use in radiation environments. A special emphasis is given to thin optical coatings, optical fibers, and fiber Bragg gratings. Here the test procedures are much more challenging than for bulk materials. The challenges... Continue reading
Space is a harsh environment due to vacuum, UV, temperature, vibration and radiation…etc. Before landing a space vehicle, devices and materials have to be tested at ground level in order to estimate the effect of all these parameters to know about irradiators. This is why, it is... Continue reading

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... Continue reading
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... Continue reading
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... Continue reading
