Description

Full text: Few approaches for surface emitting THz Quantum cascade Lasers (QCL) demonstrated the lasing of a second-order Bragg metallic grating patterned on top of a ridge or a surface emitting photonic crystal (PhC). PhC band-edge lasers with improved performance compared to Fabry-Perot lasers have already been reported. In this work a surface emitting band edge 2D PhC QCL is presented, using a second-order Bragg grating as a boundary condition. We show single mode devices operating around 3.1 THz with a maximum operating temperature of 125 K in pulsed operation, 100 K in CW, a far-field divergence of less than 20° or up to 12 mW of peak output power.
