摘要 | A photonic quantum ring (PQR) laser includes an active layer having a multi-quantum-well (MQW) structure and etched lateral face. The active layer is formed to be sandwiched between p-GaN and n-GaN layers epitaxially grown on a reflector disposed over a support substrate. A coating layer is formed over an outside of the lateral faces of the active layer, and upper electrode is electrically connected to an upper portion of the n-GaN layer, and a distributed Bragg reflector (DBR) is formed over the n-GaN layer and the upper electrode. Accordingly, the PQR laser is capable of oscillating a power-saving vertically dominant 3D multi-mode laser suitable for a low power display device, prevent the light speckle phenomenon, and generate focus-adjusted 3D soft light. |
其他摘要 | 光子量子环(PQR)激光器包括具有多量子阱(MQW)结构和蚀刻侧面的有源层。形成有源层以夹在p-GaN和n-GaN层之间,所述p-GaN和n-GaN层外延生长在设置在支撑衬底上的反射器上。在有源层的侧面的外侧上形成涂层,并且上电极电连接到n-GaN层的上部,并且在n-GaN层上形成分布式布拉格反射器(DBR)和上电极。因此,PQR激光器能够振荡适用于低功率显示装置的省电垂直显性3D多模激光器,防止光斑现象,并产生焦点调节的3D柔光。 |
