论文摘要
光子晶体表面发射激光器（PCSEL）的关键优势是通过缩放排放区域增加输出功率的同时，同时可以缩小高质量的单模式发射，从而使它们能够缩小半导体激光器和气体和光纤激光器之间存在的亮度间隙。但是，单个PCSEL设备的尺寸和功能有实际的限制，并且单模稳定性与平面内损耗之间的权衡，设备尺寸增加。在本文中，我们讨论了2D相干阵列，作为PCSEL的区域和相干功率缩放的方法。我们在两个和三个元素PCSEL阵列中证明了由于平面内损耗的降低，因此系统的差异效率提高。
A key benefit of photonic crystal surface emitting lasers (PCSELs) is the abillity to increase output power through scaling the emission area while mainting high quality single mode emission, allowing them to close the brightness gap which exists between semiconductor lasers and gas and fibre lasers. However, there are practical limits to the size, and hence power, of an individual PCSEL device and there are trade-offs between single-mode stability and parasitic in-plane losses with increasing device size. In this paper we discuss 2D coherent arrays as an approach to area and coherent power scaling of PCSELs. We demonstrate in two and three element PCSEL arrays an increase in the differential efficiency of the system due to a reduction in in-plane loss.
