中文摘要：
研究了光子晶体波导对垂直腔面发射激光器（VCSEL）光束远场形貌的调控. 采用三层对称平板波导模型分析了影响光子晶体VCSEL（PC-VCSEL）远场发散角的参数.研究表明,PC-VCSEL中光子晶体的填充比（空气孔直径和光子晶体周期的比值）以及空气孔的刻蚀深度控制了光束的发散角，低填充比和浅刻蚀的PC-VCSEL有利于获得低发散角的光束. 设计并制作了两种不同结构参数的PC-VCSEL，这两种器件中光子晶体的填充比和空气孔的刻蚀深度不同. 实验结果表明，低填充比和浅刻蚀的PC-VCSEL的发散角更低，与理论分析符合得很好.
英文摘要：
The control of the photonic crystal waveguide over the beam profile of vertical-cavity surface-emitting lasers is investigated. The symmetric slab waveguide model is adopted to analyze the control parameters of the beam profile in the photonic-crystal vertical-cavity surface-emitting laser （PC-VCSEL）. The filling factor （the ratio of the hole diameter to the lattice constant） and the etching depth control the divergence angle of the PC-VCSEL, and the low filling factor and the shallow etching depth are beneficial to achieve the low-divergence-angle beam. Two types of PC-VCSELs with different filling factors and etching depths are designed and fabricated. The experimental results show that the device with a lower filling factor and a shallower etching depth has a lower divergence angle, which agrees well with the theoretical predictions.
