By combining optoelectronics with electronics, optoelectronic integration is the challenging merger of many different areas of science and technology. This text presents the basic physics, materials, fabrication techniques, and systems applications of optoelectronic integration in a concise and organized form. This book: describes fundamental device physics and III-V semiconductor growth and processing; covers the basic design and integration of lasers, photodetectors, waveguides, and transistors; reviews and analyzes optoelectronic integrated circuits (OEICs), photonic integrated circuits (PICs), and vertical optoelectronic functional device arrays; discusses packaging and systems architecture for applications in optical telecommunications, interconnections and signal processing. With numerous cross-references, end-of-chapter references and extended summaries identifying key issues and prospects in each technical area, the text should be a useful reference for engineers, scientists and students working in optoelectronics.
