摘要：

This talk will focus on the recent efforts at the Center for Quantum Devices to deliver a high average power quantum cascade laser source at lambda similar to 6 mum. Strain-balancing is used to reduce leakage for these shorter wavelength quantum cascade lasers. Further, the effect of reducing the doping in the injector is explored relative to the threshold current density and maximum average output power. Lastly, to demonstrate more of the potential of these devices, epilayer down bonding is explored as a technique to significantly enhance device performance. (C) 2003 Elsevier Science Ltd.
