Broadband semiconductor terahertz laser based on heterogeneous cascades
We present a development of a broad gain heterogeneous quantum cascade laser for terahertz frequencies. By placing appropriate different active-regions based on a four-quantum-well design into a double-metal waveguide we obtained laser emitting gapless over a bandwidth of 1 THz, between 3.2 to 2.2 T...
