Highly Power-Efficient Quantum Cascade Lasers with Ultra-Strong Coupling Injection
Princeton Docket # 09-2561 The transport of electrons from the injector ground level to the upper laser level in the active region of a QC laser significantly influences the laser performance. The stronger the coupling between these two levels, the faster electrons can be transferred into the active region, the better is the performance...

Low-Cost Single-mode Quantum Cascade Lasers
Princeton Docket # 10-2622 Currently available commercial single-mode QC lasers either employ distributed feedback or external cavity technique to achieve single-mode emission. Due to the complexity and yield issue of these techniques, the costs and thus the sale prices for single-mode QC lasers are very high, which is a crucial barrier...
