2025-07-02 Silicon-based polarization beam splitters with broadband subwavelength grating TM-pass polarizers doi:10.57760/sciencedb.27396 en Polarization beam splitters (PBSs) are key components for polarization management in photonic integrated circuits. In this work, we demonstrate a novel silicon-based PBS with a broadband subwavelength grating (SWG) TM-pass polarizer. The experimental results show that less than 1 dB insertion loss (IL) and more than 30 dB crosstalk (CT) are realized over the wavelength range from 1500 nm to 1561 nm for both TE and TM polarizations. Our PBS can be easily integrated with other devices on standard silicon photonics platforms, with a good balance of the bandwidth, the device footprint, and the fabrication complexity. polarization beam splitters ; subwavelength grating; silicon photonics Yang Jiang Xulin Zhao Zhewei Zhang Peng Liu Ruxin Li PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset http://www.doi.org/10.1364/OE.562481 Science Data Bank
