Polarization splitter using horizontal slot waveguide
Strip-loaded horizontal slot waveguide. Single-mode and multi-mode waveguides. The loading-strip geometry dictates the properties of the channel waveguide.A polarization maintaining tapered lens fiber with an anti-reflective coating is used to couple light inside the waveguide. The focal spot of the...

Slotted Waveguide Antennas - The Antenna Theory Website An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to ...
The slotted waveguide antenna is studied. The basic principles of slot antenna arrays in waveguides are presented, along with design parameters.Using the geometry of Figure 1, the fields that exist within the waveguide are given by: In the above, f is the frequency of interest, k is the wavenumber...
The splitter is designed by finite-difference-time-domain simulation and realized experimentally. The splitter is built by using a direction coupler consisting of two horizontal slotted waveguides and achieves a high extinction ratio of 14.1 and 16.8 dB for cross and through ports. The optimal coupling length is found to be 15 µm. Vertically integrated waveguide polarization splitters ...
We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region.

Design and Optimization of Polarization Splitting and ... The configuration sketched in Figure 1 represents basic architecture of a polarization diversity circuit consisting of polarization splitters (PSs) and rotators (PRs) [21–23].In particular, at the input section the orthogonal polarization components of the input light are split into two different waveguides by using a polarization splitter (i.e., PS1). Ultrashort broadband polarization beam splitter based on a ... We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW).
