Horizontal slot waveguides for polarization branching control

Effect of Waveguide dimensions on resonant frequency of H ...

A novel compact polarization beam splitter (PBS) based on a silicon nitride–silica–silicon horizontal slot waveguide is numerically proposed, to the best of our knowledge. In the slot waveguide, the transverse electric (TE) mode propagates through the silicon layer, while the transverse magnetic (TM) mode is confined in the slot region. Control of optical mode properties in cross-slot waveguides The cross-slot waveguide geometry can be manifested as two identical horizontal slot waveguides juxtaposed side by side with a space in between, evolving to a vertical slot structure [20, 21], as ... Measurement of the Strength of Electric Fields by Means of ... The microresonators are based on stripline waveguides with vertical and horizontal slots filled with a liquid-crystal material. The mode field propagation and dispersion constants of the waveguides are calculated by the method of lines. ... “Horizontal slot-waveguides for polarization branching control,” Appl.

slots. Longitudinal slots far from the center or in the sidewall do not form good radiators [13]. 4) Slot Radiation: The ability of a slot to radiate power can be compared to a slot voltage on a transmission line. Slot voltage allows for slots to be modelled as equivalent active shunt admittance on a lossless transmission line.

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. Polarization splitter using horizontal slot waveguide Polarization splitter using horizontal slot waveguide ... In this paper a compact and efficient polarization splitter using horizontal slotted waveguides is presented. The splitter is designed by ... Polarization control and manipulation are crucial in the design and the operation of optical devices. In order to circumvent this problem, a ... Slot-waveguide - Wikipedia

We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. Waveguides oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam lithography and dry etching process. A TMAH based anisotropic wet etching technique was then used to remove any residual side wall roughness. Novel ultra-short and ultra-broadband polarization beam ...
