Abstract
Abstract Polarimetric photodetectors hold significant promise in optical communication and polarization imaging applications due to their additional ability to detect polarization states of light. The strategy of multiple states modulation plays a crucial role in performance optimization and multi‐valued logic output, enabling higher information transmission density and clearer polarization recognition. Following this context, a Ta 2 PdSe 6 /MoTe 2 semimetal/semiconductor heterojunction‐based polarimetric photodetector with multi‐control states that can enable the multi‐valued encoding communication and high‐contrast polarization imaging applications is developed. As dual‐electrically controlled states, the gate and bias voltages can significantly modulate the performance metrics. As a result, the device can be configured with tunable detectivity from 3.6 × 10 10 to 2.19 × 10 12 Jones and polarization ratios from 3.8 to 8.14 under 808 nm illumination. By further combining additional dual‐optically control states (light intensity and polarization angle), the device achieves four logic states output, thus realizing multi‐valued encoding optical communication with higher transmission efficiency and information density. Leveraging these four control states, a polarization imaging system capable of operating at different angles is also realized, with an enhanced degree of linear polarization from 0.51 to 0.8, allowing better differentiation of object features under different polarization states. This work demonstrates a polarimetric photodetector with multi‐control states, showing promising potential in high‐density communication and high‐resolution imaging applications.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
