Phase-Retrieval Coherent Detection with On-Chip Photonic Linear Processing

Mitsumasa Nakajima and Toshikazu Hashimoto

Not Accessible

Your library or personal account may give you access

Abstract

We propose phase-retrieval coherent detection with hybrid optical and digital signal processing. By using an on-chip photonic convolutional processor and digital postprocessing, 20-GBaud QPSK signals were recovered from intensity-only measurement.
