چکیده
Silicon photonics (SiPh) shows considerable potential as a radiation-hard technology for building the optical data transmission links future high-energy physics (HEP) experiments at CERN. Optical modulators are key component of links, which will need to withstand radiation doses in excess 10 MGy. The geometrical parameters and doping concentrations two popular types SiPh modulators, Mach–Zehnder ring (RMs), have been varied order study their impact on device tolerance. They were exposed an X-ray beam test resistance ionizing radiation. RM with highest concentration is shown be most tolerant, showing no degradation performance up dose 11 Moreover, we report first evidence dependence tolerance operating temperature.

Germanium Quantum Wells for High-Performance Modulators in Silicon Photonics
Silicon electronics dominates information processing, and offers a remarkable technology for making very complex systems for very little cost. Many of the waveguide passive optical components that we use today in telecommunications, such as wavelength splitters, use the same technology base – the silicon, silicon dioxide and silicon nitride that are the semiconductors and insulators of electron...
متن کاملRadiation Effects in Silicon
Any silicon device that has left the manufacturing process and goes into an application will be exposed to some degree of high-energy electromagnetic or particle radiation. Most devices, however, have seen the highest degree of exposure to particle irradiation already during the manufacturing process, the most common irradiation process being ion implantation. Less common is the exposure of sil...
متن کاملBiological Effects of Ionizing Radiation
The study of the biological effects of ionizing radiation started practically at the same time as the discovery of X-rays in 1895. Since the techniques and methods accepted today to quantify radiation dose were absent at that time, first findings and studies were barely qualitative. Nonetheless, harmful effects to man and to laboratory animal species from ionizing radiation were already observe...
