Professor John Marsh FREng

John is Professor of Optoelectronic Systems and Dean of transnational Education at the University of Glasgow.

He moved to Glasgow in 1986, where he established an internationally leading research group addressing linear and nonlinear integrated optoelectronic systems. He developed new integration technologies for photonic integrated circuits based on quantum well devices and quantum well intermixing, which ultimately led to the formation of the spin-out company Intense Ltd in 2000.

Intense developed the world’s most advanced integrated laser systems, bringing monolithic laser arrays together with electronic ASICs and optics for precise energy delivery in a range of applications from printing to material processing. The monolithic laser arrays pushed reliability and manufacturing yields to new levels.

John has extensive experience of operating in both academic and high-technology industrial environments, and as a result has an excellent understanding of spinning out IP and creating commercial value from an academic base.

He has been involved with several start-up companies including Kelvin Nanotechnology Ltd (1997-2000); Compound Semiconductor Technologies Ltd (1999-2000) and Intense Ltd (now Intense Inc) (2000-2009).

John was elected a Fellow of the Royal Academy of Engineering (FREng) in 2007; Fellow of the Royal Society of Edinburgh (FRSE) in 2000; Fellow of IEEE (FIEEE) in 2000 ‘for contributions to development of integrated optics based on semiconductor quantum well devices’; and Fellow of the Optical Society (FOSA) in 2016 for ‘for contributions to quantum and photonics technologies and systems in III-V compound semiconductors’.
