Dr John Macdonald

John Macdonald completed a BSc in Physics in 2009 and is currently a PhD student in the Nonlinear Optics Group as part of the School of Engineering and Physical Sciences at Heriot Watt University. His PhD focuses on the development of compact mid-infrared waveguide laser sources in transition metal doped II-VI semiconductors, specifically Cr2+: ZnSe and Fe2+: ZnSe. His research interests include ultrafast laser inscription of mid infrared photonic devices in zinc selenide and rare earth doped crystals and glasses.
