Horizontal slot waveguides for polarization branching control.
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. Consequently, a polarization rotator i.e., PR1 is employed in one of the waveguides to obtain a 90 rotation.

Different two-dimensional slot waveguide structures are analyzed in terms of their mode characteristics, such as the effective index, the confinement factor, and the overlap of quasi-TE and -TM modes within the slot.

The capability of polarization branching control of silicon-on-insulator horizontal slot waveguide-based directional couplers DCs was investigated, and a highly efficient polarization beam splitter PBS and a polarization-independent DC PIDC were proposed by tailoring the ratio of the coupling lengths for quasi-TE and quasi-TM modes. Due to structural birefringence, the coupling effects. In previous studies, both vertical slot waveguides [2], [3], [18] and horizontal structures [4], [19] have been demonstrated to provide tight confinement of light for TE or TM polarization, respectively. To confine light strongly in the slot region for both polarizations, novel guiding mechanism is required.

Dec 1, 2018 A polarization beam splitter PBS with a footprint of 2 2 m2 is designed. The operation bandwidth of the PBS is 40 nm, from 1528 to 1567 nm. The PBS keeps functional when designed pixel side length varies from 100 to 130 nm. Input waveguide width ranges from 300 to 350 nm is acceptable for the PBS. Keywords Particle swarm optimized.

Avertical slot waveguide confines the majority of light intothe low-index slot region due to the discontinuous bound-ary condition on the dielectric interface for the horizontalelectric field. Over the last decade, utilizing the large bire-fringence property, several slot waveguide based polariza-tion diversity devices have been proposed[10].

A compact and fabrication-tolerant polarization beam splitter PBS based on the horizontal triple-slot waveguides is proposed and optimized by using the rigorous H-field based. A full-vectorial H-field formulation-based finite element approach is used to optimize a biosensor structure incorporating a horizontal slot waveguide. It is designed to detect DNA hybridization through the change of the effective index of the waveguide structure. The key parameters, such as normalized power confinement, power density, change in effective index, and sensitivity are presented.
Polarization Splitter Using Horizontal Slot Waveguide.
A symmetric configuration is initially presented to demonstrate that the same strong confinement and propagation constants can be obtained for both polarizations and slot thicknesses down to 50 nm. To make easier further realization of these waveguides, an asymmetric waveguide configuration with a vertical slot height of up to 120 nm is proposed..

Polarisation independent silicon-on-insulator slot waveguides Valerian H Hall-Chen, Ching Eng Png The minimisation of birefringence, or polarisation mode dispersion, is vital for simplifying and miniaturising photonic components. Slotted antenna arrays used with waveguides are a popular antenna in navigation, radar and other high-frequency systems. They are simple to fabricate, have low-loss high antenna efficiency and radiate linear polarization with low cross-polarization. These antennas are often used in aircraft applications because they can be made to conform to. For example, in the polarization splitter based on hybrid plasma y-branch HPYB waveguide proposed by Hu in 2016 , Ag strip waveguides are added to the side and upper surface of the traditional y-branch waveguide respectively, so that the input TE mode and TM mode can excite the vertical and horizontal hybrid plasma modes respectively.
