摘要
En 中文
Polarization detection technology is developing toward miniaturization and high integration from the early time-division type, amplitude-division type, aperture-division type, etc., to a more integrated focal plane-integrated array type. Focal plane detectors that rely on metal nanogrids are not able to guarantee both temporal and spatial resolution for lossless polarized light detection with a guaranteed level of integration. Inspired by Agabus japonicus, the black phosphorus (BP)-based absorbing bionic stacked structured linear polarization detector (BSLD) is proposed. The BSLD exploits the polarization absorption properties of BP to achieve near-lossless linear polarization detection. The design includes two orthogonally aligned polarization- and angle-sensitive BP photodetectors. The detection performance of the detector is investigated and analyzed under a green laser beam (wavelength 532 nm). The BSLD designed in this paper can simultaneously measure the multi-angle component information of the incident light at one point in space in order to resolve the polarization state of the incident light, providing a potential solution for an integrated, real-time, and high-resolution loss-free polarization image sensor.
