Abstract Graphene, with exceptional carrier mobility and broad‐spectrum light absorption, provides a new platform for photodetection applications, thereby driving the development of next‐generation photodetectors. However, graphene photodetectors suffer from challenges such as low responsivity high noise. Due to its strong interaction density states, optoelectronic properties can be easily manipulated by local fields. Manipulation fields in is promising strategy improve detection performance expand functionality. In this review, manipulations optical are introduced, which include combination photonic structures fabrication nanostructures. Then, electric field, specifically through control electrostatic field built‐in discussed. Moreover, functional devices categorized into polarization‐sensitive photodetectors, spectral detectors, bionic devices, logic devices. Last, future perspectives summarized drive further research advanced applications.

Abstract Infrared (IR) gradient permittivity materials are the potential building blocks of miniature IR‐devices such as an on‐chip spectrometer. The manufacture with permittivities that vary in horizontal plane is demonstrated using shadow mask molecular beam epitaxy Si:InAs films. However, to be useful, needs high crystalline quality and its properties need tunable. In this paper, it shown can control length steepness by varying thickness. Samples grown similar growth parameters 200 500 µm thicknesses show widths 18 39 on flat mesa one side 11 23 film slope other side, respectively. steepnesses 23.3 11.3 cm −1 /µm 21.8 9.1 slope, for samples made masks, This work clearly shows ability in‐plane films, setting stage creation IR devices.
