Paper Abstract

We report the design and fabrication of terahertz quantum cascade lasers at about 3 THz that use semi-insulating surface-plasmon waveguide for optical mode confinement The single-mode operations are realized by employing one-dimensional first-order distributed-feedback (DFB) and photonic crystal distributed-feedback (PCDFB) resonators, respectively. The single-mode operation of up to 88 K and peak power of 9.5 mW at 10 K for the DFB devices is obtained. The PCDFB devices also emit a single frequency at above 50 K.
