摘要：

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 mu m and 12 mu m wavelengths. The results reveal the design rules for bent waveg-uides in mid-infrared astrophotonic devices.
