高偏振比日盲紫外偏振光探测器

To meet the urgent application requirements in space exploration, ultra-high-speed target tracking, and ultraviolet (UV) communication, solar-blind UV detectors are not only required to fulfill the basic criteria of high detectivity, high rejection ratio, low noise, and fast response but also need to achieve multi-optical parameter detection by integrating wavelength and polarization. Based on the in-plane anisotropy of β-Ga₂O₃, the research team led by Professor Mei Zengxia at Songshan Lake Materials Laboratory conducted crystal structure analysis, angle-resolved polarization Raman spectroscopy, and solar-blind ultraviolet polarization light detection studies. The high-performance polarization detector realized based on the anisotropic optoelectronic properties of the monoclinic β-Ga₂O₃ demonstrates the application value of β-Ga₂O₃ in the field of polarization detection. It is expected to spark a research boom in solar-blind UV polarization detection, laying an important foundation for polarization-division-multiplexing (PDM) UV optical communication, space exploration, and UV polarization imaging applications.
