Silicon is the dominating material for integrated circuits in microelectronics. Integration of optoelectronics with microelectronics will push the application in various fields ranging from high resolution imaging, infrared vision to fiber to the ...
home, to fast Ethernet, to high speed board-to board and chip-to chip connections and to more speed (above 10GHz clock frequency) in computing and system on chips, and to optical signal processing/ computing. The technical key ingredients for an integration of photonic and electronic components on silicon are the development of silicon based heterostructures (silicon germanium SiGe) and the availability of silicon on insulator (SOI) substrates. This book comprises the basics of band structure of silicon and germanium and their influence on photonic properties and discusses system layout and key device components with the application background in mind. Special focus is given to SOI based interconnects and passive waveguide devices and to germanium (Ge) on silicon (Si) heterostructure devices for light detection, modulation and emission. The high index contrast of SOI show great promise for submicron waveguide structures suited to integration on chip scale. The Ge/Si heterostructures proofed already expansion of the spectral range, high speed operation of detection, efficient modulation and switching of optical signals, and enhanced emission properties. In the research focus are chip systems with more than 100GHz speed. The book contains also an overview about the technological and material science challenges connected with the integration on Si.
