我们展示了一种半导体PCSEL阵列，它独特地结合了平面波导结构与纳米级图案化PCSEL元件。这种新颖的几何形状允许远程垂直发射激光器的二维电子可控相干耦合。通过二维杨氏狭缝实验的演示，验证了PCSEL元件的互相干性。除了允许干涉图案的全电子控制外，这种类型的器件还为半导体激光器的功率和亮度缩放提供了新的途径，并为全电子光束转向提供了机会。
We demonstrate a semiconductor PCSEL array that uniquely combines an in-plane waveguide structure with nano-scale patterned PCSEL elements. This novel geometry allows two-dimensional electronically controllable coherent coupling of remote vertically emitting lasers. Mutual coherence of the PCSEL elements is verified through the demonstration of a two-dimensional Young’s Slits experiment. In addition to allowing the all-electronic control of the interference pattern, this type of device offers new routes to power and brightness scaling in semiconductor lasers, and opportunities for all-electronic beam steering.
