High-performance operation of single-mode terahertz quantum cascade lasers with metallic gratings
A periodic array of thin slits opened on a metallic surface can act as a one-dimensional photonic crystal for the propagation of surface-plasmon waves. We have used such structure for the implementation of distributed feedback resonators in quantum cascade lasers emitting near 2.5 THz . Single-mode...
