Abstract :
The integration of photonic crystal (PC) resonators into the active region of terahertz quantum cascade lasers emitting around 2.7 THz is presented. The PC acts as frequency selective mirror and allows the tuning of the emission frequency throughout the entire gain region of the active zone. The PC and the gain region are embedded in a double-metal wave guide.
