Current Research

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.
