1. High-Speed Electroabsorption Modulators and p-i-n Photodiodes
Abstract : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. READ MORE

2. Silicon Carbide High Temperature Photodetectors and Image Sensor
Abstract : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. READ MORE

3. Near-infrared photodetectors based on Si/SiGe nanostructures
Abstract : Two types of photodetectors containing Ge/Si quantum dots have been fabricated based on materials grown by molecular beam epitaxy and characterized with several experimental techniques. The aim was to study new device architectures with the implementation of Ge nanostructures, in order to obtain high detection efficiency in the near infrared range at room temperature. READ MORE
