Summary on Grant Application Form |
The group at the University of Leeds, through funding from EPSRC, have been developing numerical models and design software for unipolar devices, in particular quantum cascade lasers, for several years. The techniques used are based on fundamental quantum mechanical scattering, from which the model of the entire laser is built. Several papers published earlier this year have demonstrated the model's ability to reproduce the physical observables of the laser output characteristics, furthermore the model reveals the internal workings of the device, leakage currents, parasitics etc. which are not readily available to the experimentalists. The group are now turning their attention to the development of entirely new device configurations. Through an informal collaboration with workers at the University of Belgrade we have developed the first design of a digitally graded active region for a quantum cascade laser that has been optimised to maximise the laser gain (this design has just been grown by our collaborators at Sheffield). We would like to strengthen the link and we seek funds, in this proposal, for our collaborators in Belgrade to make a series of short visits to Leeds. This will enable a transfer of the optimisation skills from Belgrade to Leeds, thus giving us a whole new toolset which can be applied to the design of many other optoelectronic devices.
