Silicon Photonic Direct-Detection Phase Retrieval Receiver
arXiv:2310.01674
Abstract
We demonstrate a direct-detection phase retrieval receiver based on silicon photonics. The receiver implements strong dispersion and delay lines on a compact chip. We retrieve the full field of a 30-GBd QPSK signal without a carrier or local oscillator.
