“…Polarization (POL) is the unique property of light as a transverse electromagnetic wave, reflecting that the vibration direction of the optical wave electric vector does not have symmetry with the propagation direction of light. Polarization information is valued by people in the fields of navigation [2][3][4][5], medicine [6,7], and remote sensing [8][9][10]. Navigation technology plays an important role in people's daily lives, and it is indispensable for both daily travel and industrial transportation.…”

A polarized light sensor is applied to the front-end detection of a biomimetic polarized light navigation system, which is an important part of analyzing the atmospheric polarization mode and realizing biomimetic polarized light navigation, having received extensive attention in recent years. In this paper, biomimetic polarized light navigation in nature, the mechanism of polarized light navigation, point source sensor, imaging sensor, and a sensor based on micro nano machining technology are compared and analyzed, which provides a basis for the optimal selection of different polarized light sensors. The comparison results show that the point source sensor can be divided into basic point source sensor with simple structure and a point source sensor applied to integrated navigation. The imaging sensor can be divided into a simple time-sharing imaging sensor, a real-time amplitude splitting sensor that can detect images of multi-directional polarization angles, a real-time aperture splitting sensor that uses a light field camera, and a real-time focal plane light splitting sensor with high integration. In recent years, with the development of micro and nano machining technology, polarized light sensors are developing towards miniaturization and integration. In view of this, this paper also summarizes the latest progress of polarized light sensors based on micro and nano machining technology. Finally, this paper summarizes the possible future prospects and current challenges of polarized light sensor design, providing a reference for the feasibility selection of different polarized light sensors.

“…Compared with the traditional polarization detection methods, including division of time (DoT), division of amplitude (DoAm) and division of aperture (DoA), it has the advantages of compact structure, real-time imaging and high stability. With the development of micro-/nanoprocessing technology, the DoFP polarization detection technology has become a research hotspot [ 20 , 21 , 22 , 23 , 24 , 25 ].…”

Shortwave infrared polarization imaging can increase the contrast of the target to the background to improve the detection system’s recognition ability. The division of focal plane polarization indium gallium arsenide (InGaAs) focal plane array (FPA) detector is the ideal choice due to the advantages of compact structure, real-time imaging, and high stability. However, because of the mismatch between nanostructures and photosensitive pixels as well as the crosstalk among the different polarization directions, the currently reported extinction ratio (ER) of superpixel-polarization-integrated detectors cannot meet the needs of high-quality imaging. In this paper, a 1024 × 4 InGaAs FPA detector on-chip integrated with a linear polarization grating (LPG) was realized and tested. The detector displayed good performance throughout the 0.9–1.7 um band, and the ERs at 1064 nm, 1310 nm and 1550 nm reached up to 22:1, 29:1 and 46:1, respectively. For the crosstalk investigation, the optical simulation of the grating-integrated InGaAs pixel was carried out, and the limitation of the ER was calculated. The result showed that the scattering of incident light in the InP substrate led to the crosstalk. Moreover, the deviation of the actual grating morphology from the designed structure caused a further reduction in the ER.

“…To date, nanostructures are usually obtained by electron beam direct writing (EBDW), 14,15) focused ion beam (FIB), 16,17) femtosecond-laser direct writing (FsLDW), 18,19) and nanoimprint lithography (NIL). [20][21][22] Among these well-developed nanofabrication methods, EBDW is the most prominent technology because it can make original patterns with high resolution and flexibility in photomask manufacturing and basic research. In order to further form metallic nanostructures, this method involve several other processing steps, such as depositing metal layers and some lift-off or etching processes as well.…”

“…30) Meanwhile, some metals, such as aluminum and gold, cannot be directly transferred by this method because of the weaker bonding force between metal and polymer substrate. 29) Aluminum, 3,21,22) gold, 1,16) and silver 4,11) are widely used in metallic micro-nano devices. In this letter, aluminum is selected as the material for the transfer of metallic nanostructures and the fabrication of metal grating polarizer because of its better polarization characteristics than other metal materials.…”

We propose a novel flexible contact ultraviolet (UV)-curable nano-imprint lithography process which can directly transfer metallic nanostructures by UV curing bonding force. The flexible template evaporated with metal acts as a mask, allowing only the structural region to penetrate UV light and transfer surface metallic nanostructures. By this process, aluminum metal grating of different feature sizes had been transferred to abtain single-layer or even multi-layer metallic nanostructures. The minimum width and spacing of the wire grating were 50 nm and sub-20 nm, respectively. Aluminum grating polarizer had also been fabricated and tested demonstrating the practicability of the process. © 2019 The Japan Society of Applied Physics
