Single-mode narrow beam divergence surface-emitting concentric-circular-grating terahertz quantum cascade lasers

Single-mode narrow beam divergence surface-emitting concentric-circular-grating terahertz quantum cascade lasers

Single-mode surface-emitting terahertz quantum cascade lasers with second-order concentric-circular-gratings are firstly demonstrated. The gratings are designed for single-mode operation and surface emission for efficient and directional optical power out-coupling. The first structure exhibits singl...
