研究了氧化物限制的具有表面起伏基模选择的垂直腔面发射激光器（VCSEL）的模式行为。测量了单模功率与表面起伏直径的关系，并与数值计算值进行了比较。直径为9和12 /spl mu/m的VCSEL配备有直径在4-10 /spl mu/m范围内的表面浮雕。结果表明，对于每种尺寸的VCSEL，都存在一个最佳的浮雕直径。对于直径为9 μ m/spl μ m/m且表面起伏为4 μ m/spl μ m/m的VCSEL，实现了2.2 mW的最大单模功率。
We have studied the mode behavior of oxide-confined vertical-cavity surface-emitting lasers (VCSELs) with a surface relief for fundamental mode selection. The dependence of single-mode power on the surface relief diameter was measured and compared with numerically calculated values. VCSELs with diameters of 9 and 12 /spl mu/m were equipped with surface reliefs with diameters in the range 4-10 /spl mu/m. The results show that there exists an optimum relief diameter for each VCSEL size. A maximum single-mode power of 2.2 mW was achieved for a 9-/spl mu/m-diameter VCSEL with a 4-/spl mu/m-diameter surface relief.
