Asymmetric Silicon Slot-Waveguide-Assisted Polarizing Beam Splitter PROJECT TITLE :Asymmetric Silicon Slot-Waveguide-Assisted Polarizing Beam SplitterABSTRACT:A silicon polarizing beam splitter is designed and fabricated based on an uneven slot waveguide structure while not adopting additional strip-slot waveguide mode converters. The uneven slot waveguide consists of a 150-nm-wide and a 350-nm-wide nanowires with a slot of one hundred nm, which can notice a transverse magnetic lightweight cross-coupling with a 392-nm-wide strip waveguide, whereas very little transverse electric lightweight coupling can happen. The fabricated device has a coupling length of with a coupling gap spacing of 450 nm, that can achieve a polarization extinction ratio (PER) of and 25 dB at the bar and cross ports, respectively. Low insertion loss is realized, while additional than 10-dB PER can be obtained over the wavelength range of 1520–1576 nm. The device performance might be further improved with the fine optimization of device structure parameters and fabrication process. Did you like this research project?
