Realization of a Flat-Band Superprism On-Chip from Parallelogram Lattice Photonic Crystals
Digital Object Identifier (DOI)
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.
