Complete coverage of the field of silicon-based photonic devices, including a chapter on nonlinear silicon photonics Silicon Photonics discusses the physics, technology, and device operation of photonic devices using silicon, Group IV semiconductors, and their alloys. The book delivers an optimal combination of background information about photonic structures with description of up-to-date results and trends in silicon photonics. This Second Edition includes a new chapter on nonlinear silicon photonics as well as numerous updates to existing content. Readers will find information on the role of silicon in photonics and its advantages and disadvantages as well as the properties of these alloys. Subsequent chapters in Silicon Photonics explore topics including: Quantum structures, covering quantum wells, wires, and dots, superlattices, Si-based quantum structures, and effects of electric fields Optical processes, covering absorption processes in semiconductors, intervalence band absorption, free-carrier absorption, and recombination and luminescence Si light modulators, covering electrorefraction, thermo-optic effects, modulators, and optical and electrical structures Raman lasers, covering Raman scattering, the Raman effect in silicon, the Raman gain coefficient, and continuous-wave Raman lasers Principles of planar waveguide devices, covering directional couplers and distributed Bragg reflectors Silicon Photonics is an excellent resource on the subject for materials scientists, applied physicists, electrical engineers, and postgraduate students working in Si photonics.
