New preprint: Holistic nanowire laser characterization as a route to optimal design

Left – microscopic imaging, centre – optical spectroscopy and right – time-resolved spectroscopy. All measurements are on a single nanowire laser.

Group postdoc Stephen Church has submitted his most recent work to the arXiv preprint server. In this new work, Stephen carried out optical, microscopic, and electron micrograph characterization of over 5000 nanowire lasers. By correlating geometry effects which affect the nanolaser cavity, and material quality that affect gain material, we show that surprisingly material quality remains the limiting factor for low-threshold and high yield operation.
