摘要

本研究在天文N波段(8 ~ 12 μ m波段)数值计算了由as2se - 3芯和as2se - 3下包层组成的硫系玻璃通道光波导的弯曲损耗。研究结果揭示了中红外天体光子器件弯曲波导的设计规律。

Bending Loss Analysis of Chalcogenide Glass Channel Waveguides for Mid-Infrared Astrophotonic Devices

SUMMARY In this study, the bending losses of chalcogenide glass channel optical waveguides consisting of an As 2 Se 3 core and an As 2 S 3 lower cladding layer were numerically evaluated across the astronomical N -band, which is the mid-infrared spectral range between the 8 μ m and 12 μ m wavelengths. The results reveal the design rules for bent waveguides in mid-infrared astrophotonic devices.
