In this study, we conduct guided mode analyses for chalcogenide glass channel waveguides using As₂Se₃ core and As₂S₃ lower cladding to determine their single-mode conditions across the astronomical N-band (8 — 12μm). The results reveal that a single-mode operation over the band can be achieved by choosing a suitable core-thickness.
