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路。我们已经实现了二氧化硅平面光波电路的小弯曲结构。沿核心区域有深沟槽，并填充低折射率材料；因此，增加了光学限制并提供了低损耗的小弯曲。我们使用所提出的结构制造了小型阵列波导光栅，它有8个输出通道，频率间隔为100 GHz。插入损耗为4. 47 dB，偏振相关损耗为0.25 dB，串扰为26.3 dB。开发了使用集成环镜的阵列波导光栅。通道间距、偏振相关损耗和相邻串扰分别为 10.9 dB、0.1 dB 和 8.2 dB。
