Abstract: Monolithic integration is a critical technology for enabling the widespread adoption of high-speed optoelectronics, particularly in price sensitive applications. Although the range of materials used in optoelectronic sub-systems is a break on realizing truly monolithic solutions, considerable advances have been made in the III-V semiconductor materials based on InP and GaAs. Photonic Integrated Circuits containing hundreds of components are now routinely manufactured. Integration of components in a serial configuration has led to the development of sub-systems with significantly enhanced functionality, which is highly appropriate for systems with multiple channels operating in parallel, such as WDM and CWDM communications systems. Examples of these range from integrated laser modulators through to high frequency mode-locked lasers with applications such as high-speed OTDM and microwave/THz over fiber.In this talk, the technologies and methodologies for monolithic integration will be described, with an emphasis on wafer design and low-cost fabrication that requires only a single stage of epitaxy. Examples of sub-systems that exploit parallel and serial integration will be given, focusing on laser arrays, CWDM sources and mode-locked lasers.

Biography：John Marsh is Head of the School of Engineering and Professor of Optoelectronic Systems at the University of Glasgow. He has more than 30 years’ experience of semiconductor laser technology in the high technology and higher education sectors, ranging from epitaxial growth through to the development and manufacture of complete laser modules. He was a founder of Intense Photonics Ltd in 2000, serving as its Chief Technical Officer until August 2011. His work includes research into the fundamental electrical and optical properties of semiconductors, development of novel optoelectronic devices, processes for creating photonic integrated circuits, integrated mode-locked lasers for ultra-short pulse generation, and development and manufacturing of high-power laser array products. John is a graduate of the Universities of Cambridge (BA), Liverpool (MEng) and Sheffield (PhD). He has published more than 480 papers in journals and conferences and holds a number of patents. He is a Fellow of the Royal Academy of Engineering, Royal Society of Edinburgh, IEEE, Institution of Engineering and Technology (UK), Institute of Physics and Royal Society of Arts. He received the 2006 IEEE/LEOS Engineering Achievement and the 2006 IEEE/LEOS Distinguished Service Awards. He was President of the IEEE Photonics Society in 2008 – 2009 and is currently a member of the Board of Governors of the IEEE Technology Council.
