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.Surface emitting Terahertz Photonic Crystal Quantum Cascade Laser realized by Bragg boundary conditiontext::conference output::conference proceedings::conference paper
