Dr Graeme Brown
Graeme Brown was awarded his MPhys (Hons) degree in Physics with Laser Science from Heriot-Watt University in 1997. He completed his PhD on Time-Resolved Ultrafast Spectroscopy of Wide Gap II-VI Semiconductor Quantum Wells in 2001, also at Heriot-Watt. From 2000-08 he worked in the optoelectronics industry in the development of new telecommunication components and advanced optical test systems. In 2009 he returned to Heriot-Watt and led the technical development on a Scottish Enterprise Proof-of-Concept on the commercialisation of ultrafast laser inscription for sensing applications. He is currently a research associate working on the development of integrated, compact laser sources fabricated by laser inscription. Part of this work is the development of integrated modelocking elements based on saturable absorbers such as graphene and carbon-nano-tubes.
He is Co-Founder of a spin-out company, Optoscribe, which is commercialising the research groups work in ultrafast laser inscription.
