- Abstract
- The detection of light polarization is crucial in optical networks, which currently rely on complex modules comprising a series of optical and electronic elements, such as lenses, polarizers, waveplates, and filters, thereby hindering miniaturization and integration for compact systems. Here, we developed a miniaturized self-driven polarimeter designed with a semiconducting transition metal dichalcogenide (TMD) and a ring-shaped electrode. Under perpendicular illumination, the edge plasmon at the metal/MoS2 interface is excited, consequently enhancing photoresponse significantly. Building on this phenomenon, a ring-shaped electrode structure has been designed, enabling the direct visualization of the polarization of the incident light, with the ability to reconstruct the polarization angle with a root-mean-square error of similar to 2 degrees at 532 nm. The simple design and ultracompact structure of our developed polarimeter may inspire the development of high-performance polarization-resolvable optoelectronic platforms.
