By optimizing the structural parameters of the fiber, a terahertz polarization beam splitter with a bandwidth of 0. Reconfigurable beam splitters capable of being arbitrarily programmed for the power splitting ratios are vital for the adaptive optical networks and photonic computing. Conventional mechanisms such as thermo-optic, free-carrier, or mechanical tuning are usually volatile and require continuous. 1×2 1310/1480/1550nm Polarization Beam Splitter (PBS) is a high-precision optical device that can split input light into P-polarized light and S-polarized light according to the polarization state of the light. It is suitable for three common communication wavelengths of 1310nm, 1480nm and 1550nm. To address the demand for low-cost, low-loss, and environmentally friendly optical power dividers in short-range visible light communication (VLC) systems, a low-loss 1 × 2 Y-branch optical splitter based on the integration of a planar optical waveguide (POW) and plastic optical fiber (POF) is. This paper proposes a polarization beam splitter operating at terahertz frequencies.
