We present the design and fabrication of highly reflective and low loss multilayer dielectric mirrors (SiO_2/ZrO_2) for GaN based vertical cavity surface emitting lasers (VCSELs). We consider two types of VCSEL structures ; one consists of AlN/GaN vertical cavity structure with a cavity length of 1.9 μm has been demonstrated. The other consists of two dielectric mirrors (SiO_2/ZrO_2) with a polished thin sapphire substrate. A resonant emission forma photo-pumped GaInN/GaInN vertical cavity with a spectral line width of 3.8 nm has been demonstrated. Also, we propose a new structure using lateral growth on dielectric Mirrors as a bottom reflector. We have demonstrated and characterized the thin GaInN/GaN 10 MQWs fabricated by removing a sapphire substrate with UV light irradiation for making a micro-cavity structure. The PL properties of standing-alone QWs show no noticeable degradation of QWs after the removing process. We pointed out the importance of the flatness of removed interfaces.

我们为基于GAN的垂直腔表面发射激光器（VCSELS）的高度反射性和低损失多层饮食镜（SIO_2/ZRO_2）的设计和制造。我们考虑两种类型的VCSEL结构。一种由ALN/GAN垂直腔结构组成，腔长为1.9μm。另一个由两个饮食镜（SIO_2/ZRO_2）组成，带有抛光的蓝色蓝宝石底物。已经证明了光谱线宽度为3.8 nm的共振发射形式的光泵振幅增益/增益垂直腔。另外，我们提出了一种新的结构，该结构使用顽固镜上的横向生长作为底部反射器。我们已经证明并表征了通过拆下带有紫外线照射的蓝宝石底物来制造微型腔结构的蓝色Gainn/gan 10 MQW。站立QW的PL性质在去除过程后没有明显的QW降解。我们指出了去除接口的平坦度的重要性。
