Abstract

Polarization aberrations reduce the polarization-maintaining performance of optical systems. This degradation adversely affects detection accuracy in laser communication, which necessitates suppression. In this paper, a novel approach is proposed to address this issue by integrating metasurfaces into the optical system design. Simulation results indicate that after implementing the hybrid design, the average diattenuation of the optical system is reduced by 91.8%, and the average retardance is reduced by 95.0%. This design method is shown to significantly enhance the polarization-maintaining performance of optical systems. As an innovative application of metasurfaces, this design markedly improves the coherent mixing efficiency in laser communication.

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
