In this study, the bending losses of chalcogenide glass channel optical waveguides consisting of an As₂Se₃ core and an As₂S₃ lower cladding layer were numerically evaluated across the astronomical N-band, which is the mid-infrared spectral range between the 8 μm and 12 μm wavelengths. The results reveal the design rules for bent waveguides in mid-infrared astrophotonic devices.
