Fig. 2

a The 2-dimensional band structure. The black arrow shows the single-mode region. The inset shows one corner of the bent waveguide. b The transmittance spectra of the straight W1WG (black curve) and Z-shaped W1WG. The average transmittance is 0.47, and the F-P reflectivity is 0.40. c The out-of-plane magnetic field Hz of the Z-shaped W1WG at a/Ī»ā€‰=ā€‰0.270. The transmittance is 0.39. The five-pointed star indicates the location of the wave source. The arrow points toward the propagation direction.
