本文报道了砷化镓（GaAs）/空气分布布拉格反射器微谐振器的制作，该微谐振器采用砷化铟镓量子威尔斯阱结构。的结构进行了研究，通过动量分辨的光致发光光谱，使我们能够调查一个明显的光学模式量子化的光子色散。我们可以从这些量子化态中提取一个长度参数，其上限可以通过解析计算与微腔的横向物理延伸相联系。在功率依赖的研究中观察到了光泵浦下微腔的激光发射。
We report on the fabrication of gallium arsenide (GaAs)/air distributed Bragg reflector microresonators with indium gallium arsenide quantum wells. The structures are studied via momentum resolved photoluminescence spectroscopy which allows us to investigate a pronounced optical mode quantization of the photonic dispersion. We can extract a length parameter from these quantized states whose upper limit can be connected to the lateral physical extension of the microcavity via analytical calculations. Laser emission from our microcavity under optical pumping is observed in power dependent investigations.
