Published on 30 August 2017 in Scientific Reports, ‘Monolithically multi-color lasing from an InGaN microdisk on a Si substrate  is the result of a collaboration between the University of Sheffield and the University of Bristol and is supported by an EPSRC grant.

“This work demonstrates a novel approach towards realising monolithically grown white light lasers using III-nitride material. The small size and the simplicity of the micro-disk structure, which can simultaneously support number of high-Q resonances, makes this approach very attractive for potential applications.”  Dr Modestos Athanasiou, Research Associate

The applications include full colour high definition displays, next generation vehicle headlighting, biosensors, visible light communications or even lighting.
