Fabrication of Surface-Emitting Laser Array

我们考虑了一些可能的应用，包括光互连、并行光纤子系统等，具有高功率和大量扩展的二维阵列。为了实现相干阵列，我们尝试了使用talbot腔来实现这些阵列激光器的相干耦合，并考虑了相位补偿。指出二维阵列比线性阵列更适合制作相干阵列，因为我们可以利用二维对称性的优势。目前，利用SE激光光电路的小腔尺寸的优势，将研究方向转向基于SE激光光电路的单片集成。密集排列阵列也被证明用于制造高功率激光器和相干阵列。

We consider some possible applications including optical interconnects, parallel fiberoptic subsystems, and so on by featuring high power capabilities and largely extending 2-D arrays, For the purpose of realizing coherent arrays, coherent coupling of these arrayed lasers has been tried by using a talbot cavity and phase compensation is considered. It is pointed out that 2-D arrays are more suitable to make a coherent array than a linear configuration, since we can take the advantage of 2-D symmetry. The research activity is now forwarded to monolithic integration of SE laser based optical circuits by taking the advantage of its small cavity dimension. Densely packed arrays have also been demonstrated for the purpose of making high power lasers and coherent arrays.
