摘要
量子级联激光器(qcl)是中红外区域许多基于激光的应用的首选光源。光子晶体(PhC)-QCL[1]由于其独特的二维平面内耦合机制，在模式选择、表面发射和光束控制等方面具有优越的优势。在这项工作中，我们提出了一个在室温(289 K)脉冲模式下工作的大面积(1.5 mm × 1.5 mm) PhC-QCL，表面发射峰值功率高达1 W。
Large Area Surface-Emitting Photonic Crystal Quantum Cascade Laser
Quantum cascade lasers (QCLs) are the sources of choice for many laser-based applications in the mid-infrared region. Because of the unique 2D in-plane coupling mechanism, a photonic crystal (PhC)-QCL [1] has superior advantages on mode selection, surface emission, and beam control. In this work, we present a large-area (1.5 mm × 1.5 mm) PhC-QCL operating under pulsed mode at room temperature (289 K). The surface-emitting peak power is as high as 1 W.
