Horizontal slot waveguides for polarization branching control

The silicon cross-slot waveguide presented here is taken from an article from Helsinki University of Technology [1], featuring FIMMWAVE simulations. The paper also presents results for waveguide geometries with angled sidewalls. Frontiers | Low-Loss Slot Waveguides with Silicon (111)… We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform.This slow etching of the (111) plane can also be used to precisely control the slot width by simply optimizing theIn most applications, the slot waveguides are cladded with low index materials, such as polymers (Koos...

index layers [1]. Comparing with conventional waveguides, slot waveguides exhibit unique optical properties. In a slot waveguide, strong optical confinement is achieved in the intermediate low-index layer. Several configurations of slot waveguides have been demonstrated, including vertical slot waveguides [2], horizontal slot waveguides [3 ...

When using horizontally polarized BiQuads, or Patch antennas (provided that they have been tested for good cross- polarization performance) at the client site, these omnisBut, if a 16 slot waveguide antenna is turned to a horizontal position, parallel with the ground, it will radiate vertical polarization.

In waveguide technology, bethe-hole and short slot couplers are widely used. This project is more concentrated onFigure 3-4 Cross-sections of the groove gap waveguide for vertical and horizontal Polarizations forTo control all these factors we have introduced pucks in the waveguide, which...

ent in SOI waveguides, polarization diversity circuits consisting of a polarization splitter to allow TE and TM signals to be processed separately is often used. This can be utilized in con-junction with polarization rotators, which can ensure that the signal is launched into a given device with the appropriate state of polarization [5], [6]. T-shaped dielectric slot waveguides for efficient control of ... Due to the relatively small overlap between the two polarized modes and enhanced regions occurring at different parts of the T-slot structure, the relatively independent control of the two polarization modal properties becomes possible. For example, the upper vertical slot region and/or the horizontal one can be filled with index-tunable materials. Alvin Ma - Development Engineering Manager - Intel ...
