This prediction of a fundamental asymmetry between the corners that underlies the behavior in Figure ,b is dramatically visualized in Figure , which depicts a stream plot of the Poynting vectors overlaid on the bent topological waveguide. Near the more robust majority-trivial corner, the bulk of the Poynting vectors (densely spaced blue lines) from the lower part of the waveguide are clearly seen to essentially avoid the C2v unit cell (orange circle) and flow around the bend through the adjacent topological unit cell (black circle) facilitating robust propagation resistant to interfacial defects at the corner (red highlighted sites). In contrast, the Poynting vectors near the more sensitive majority-topological corner (highlighted by the blue arrow) show that the mode largely propagates thro ugh the C2v unit cell (green circle) reducing the topological protection due to the lack of local C6 symmetry. Said another way, transmission through the topological waveguide can be thought to be insensitive to defects in the majority-trivial corner (red highlighted sites) because the energy flow essentially avoids them, whereas defects in the majority-topological corner (blue highlighted sites) are damaging to transmission (Figure ) because energy flows directly through these sites. Based on our analysis, we estimate that the majority-trivial corner of our bent waveguide is 3 to 5 times more robust to geometric disorder than that used in the majoritytopological corner and thus offer a new empirical design rule for pseudo-spin Hall TI-based bent waveguides, and a more practical geometry for use in photonic devices such as resonators.
