High Quality Tunable Graphene Plasmonic Metamaterials
Abstract
The project demonstrated the first large-scale, fully tunable integrated photonic circuits. The resulting ultra-dense, fully controllable array of free space optical signals has potential applications in fields such as LiDAR, beam forming and steering, optical interconnects, microscopy, and neural networks. The development of an optically controlled SLM with high-speed performance and high pixel density offers new opportunities for optical wavefront shaping, enabling breakthroughs in fields such as biomedical imaging, telecommunications, and quantum information processing. We developed a nanopatterned electrolyte gating technique that creates high carrier density variations at the nanometer scale, using a resist mask and cross-linked poly(methyl methacrylate). We demonstrated the technique by fabricating a compact mid-infrared graphene thermopile that can pave the way for more compact high-speed thermal detectors and cameras.
