Summary on Grant Application Form |

This research has the overall aim to achieve significant reductions in carrier leakage in AIGaInP lasers using MQB structures to enable manufacturable 630nm lasers to be made with acceptable threshold current density and much reduced temperature sensitivity of threshold current. The key elements o this research are that (i) the reflectors are designed to take account of carrier loss through the X conduction band minima, (ii) the grown structures are being evaluated by scanning probe microscopy/spectroscopy to measure the quantum mechanical enhancement and (iii) direct measurements are beir made of carrier leakage. We propose to introduce new features in the design to enable the structures to be manufactured using current commercial growth techniques.
