Research output: Chapter in Book/Report/Conference proceedingConference contribution


We demonstrate a quantum cascade laser featuring a low-voltage-defect short injector. Devices showing a voltage-defect as low as 20meV and voltage efficiency of 88% at 80K are reported, with >80% voltage efficiency at room temperature.
