By optimizing the dispersion curve of a parallelogram-based 2D photonic crystal superprism for constant angular group velocity dispersion over a broad bandwidth, we designed a device capable of experimentally demonstrating linear dispersion from 1500 to 1600 nm with clear separation of as many as eight channels, while maintaining a compact footprint.
通过优化基于平行四边形的二维光子晶体超棱镜的色散曲线，实现了在宽带宽范围内恒定角度群速度色散，我们设计了一种能够在实验中演示从 1500nm 到 1600nm 线性色散的器件，具有多达 8 个通道的清晰分离，同时保持紧凑的占地面积。
