2020年7月22日 · In this work, we demonstrate an edge coupler (EC) for the coupling between the single mode fiber (SMF) and the silicon photonic waveguide. High coupling efficiency can be achieved by using arrayed waveguides at 1550 nm with an un-patterned cladding.
SMF-28 fiber mode calculation - Ansys Optics
To do so, we must first disable the symmetry BC's, so we find all supported modes. Next, re-run the solver at a much shorter wavelength (such as 1um) where the device is known to be multi-mode. Next, switch to the frequency sweep tab and run a sweep, tracking all modes, from 1um to 1.55um. The results are shown below.
