Abstract

We present the design and experimental evaluation of low-loss advanced bends in silicon nitride (SiN) waveguides for the C-band. The advanced bends, with a radius of 25 μm, exhibit a bending loss of approximately 0.025 dB per 90°, comparable to the loss of a circular bend with a radius of 50 μm. Consequently, the 25 μm radius advanced bend is proposed for routing in SiN photonic integrated circuits to reduce the overall footprint. Furthermore, the use of these advanced bends in micro ring resonators results in quality factors of 5.8 × 10 ³ and 5.5 × 10 ⁴ , with relatively large free spectral ranges and extinction ratios for radii of 15 μm and 25 μm, respectively.

c波段氮化硅光子波导中的先进弯管和微环谐振器

本文介绍了c波段氮化硅（SiN）波导低损耗高级弯曲的设计和实验评估。先进的弯曲管半径为25 μm，每90°弯曲损失约为0.025 dB，与半径为50 μm的圆形弯曲管的损失相当。因此，提出了25 μm半径的先进弯曲布线在SiN光子集成电路，以减少整体占地面积。此外，在微环谐振器中使用这些先进的弯头，质量因子分别为5.8 × 103和5.5 × 104，在半径为15 μm和25 μm时，具有较大的自由光谱范围和消光比。
