Abstract: Polarization splitter (PBS) consisting of a hybrid plasma horizontal slot waveguide (HSW) and silicon nitride vertical (VSW).At suitable HSW VSW widths, the TE polarization modes in are phase-matched, while TM phase mismatched. The results show that PBS achieves an extinction ratio (ER) 35.1 dB insertion loss (IL) 0.34 for mode at 1.55 μm, For mode, reached 40.9 ER 2.65 IL.

The design, fabrication, and characterization of a silicon nitride waveguide polarization rotator beam splitter that operate with extinction ratio (PER) ∼30 dB at the rubidium atomic transition 780 nm wavelength are demonstrated. These devices fabricated on same chip using self-aligned process for integration rib ridge structures. is based mode evolution approach adiabatic tapers demonstrates P...

We report experimental results with a reflective continuous anisotropic polarizing diffraction-grating beam splitter that produces three diffraction orders. The diffraction efficiencies and polarizations of the diffracted orders are controlled through the incoming polarization state and by use of a wave plate with arbitrary orientation located between the grating and a mirror. In particular, we...
