Abstract

A low-loss waveguide bend is experimentally demonstrated to reduce the loss in a circular bend from 0.372 ± 0.032 dB to 0.016 ± 0.003 dB. Moreover, A ring resonator based on this design is demonstrated with an FSR of 21.51 ± 0.01 nm in the O-band while keeping a low ring internal loss of 0.038 ± 0.003 dB.

低损耗波导弯曲支持低语画廊模式

实验证明了一种低损耗波导弯曲可以将圆弯曲的损耗从0.372±0.032 dB降低到0.016±0.003 dB。此外，基于该设计的环形谐振器在o波段的FSR为21.51±0.01 nm，同时保持了0.038±0.003 dB的低环内损耗。
