The purpose of the project is to develop high-resolution optical circuit for next generation photonic networks. We have realized small bend structure for silica planar lightwave circuits. It had deep trenches along core region and they were filled with low-refractive index materials ; therefore, the optical confinement was increased and low-loss small bend was provided. We fabricated small arrayed-waveguide grating using the proposed structure, it had 8 output channels with a frequency spacing of 100 GHz. The insertion loss was 4. 47 dB, the polarization dependent loss was 0.25 dB, and the crosstalk was 26.3 dB, respectively. The arrayed-waveguide grating using integrated loop mirrors was developed. The cannel spacing, the polarization dependent loss, and the adjacent crosstalk were 10.9 dB, 0.1 dB, and 8.2 dB, respectively.

该项目的目的是为下一代光子网络开发高分辨率光电路。我们实现了二氧化硅平面光波电路的小弯曲结构。沿核心区有较深的沟槽，沟槽内填充着低折射率材料；因此，增加了光约束，提供了低损耗小弯曲。我们利用所提出的结构制作了小型阵列波导光栅，它有8个输出通道，频率间隔为100ghz。插入损失为4。偏振相关损耗为0.25 dB，串扰为26.3 dB。研制了一种集成环形反射镜阵列波导光栅。通道间距、极化相关损耗和相邻串扰分别为10.9 dB、0.1 dB和8.2 dB。
