My current research focus is the development of GaSb quantum-ring vertical-cavity surface-emitting lasers. More generally my research interests cover the design and fabrication of semiconductor devices utilising quantum nanostructures (quantum wells, wires, dots and rings).

My current research focus is the development of GaSb quantum ring (QR) vertical-cavity surface-emitting lasers (VCSELs). The majority of production VCSELs emit at <1000nm, through use of GaSb QRs we have wavelength targets including telecoms wavelength (~1300nm and 1550nm), and so-called 'eye-safe' emission >1400nm for smartphone sensing and LiDAR.
