Abstract :
We theoretically and experimentally investigate a band edge Photonic Crystal (PhC) Quantum Cascade Laser (QCL) operating at 3.1 THz. The surface emission is achieved by using a second-order Bragg grating at the PhC tile boundaries. Highly directional surface emitting far-field patterns are observed.
