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.

Polarization properties of two-dimensional slot waveguides. / Khanna, Amit; Säynätjoki, Antti; Tervonen, ... Conventional horizontal and vertical slot waveguides can only provide high slot confinement for either the quasi-TM or quasi-TE modes, respectively. Different two-dimensional slot waveguide structures are analyzed in terms of their ... Design and Simulation of Compact Optical Modulators and ... Design and Simulation of Compact Optical Modulators and Switches Based on Si–VO2 –Si Horizontal Slot Waveguides Abstract: In this paper, a horizontal slot Si-VO 2 -Si optical waveguide is proposed and its optical properties are investigated. Polarization splitter using horizontal slot waveguide. The optimal coupling length is found to be 15 µm. The device exhibits a good response of extinction ratio across C + L broadband. The splitter obtained is readily used for a polarization diversity circuit, particularly for platforms with horizontal slot waveguides. PMID: 23481796 [PubMed - indexed for MEDLINE] Publication Types: Ultracompact, broadband slot waveguide polarization splitter can be achieved in slot waveguides,7 and such slot wave-guide birefringence has been leveraged for polarization-independent directional coupling.8,9 Figure 1 shows a top view schematic of the polarization splitter device. It consists of a fiber-waveguide coupler for efficient channeling of the mixed-polarization light from an

Hi members, am new to antenna field.I would like to know more about polarization in waveguide.As per book,it is stated that TEM wave cannot travel in waveguide.If that is the case how come horizontal or vertical polarization can be achieved.If am wrong,please correct me.Thanks in advance. I'm not ...
