Optical De-aggregation from 9QAM to PAM3 using Phase-sensitive Amplifier-based Optical Quadrature De-multiplexing and Two-level Vector Moving

An optical de-aggregation scheme based on quadrature de-multiplexing and vector moving is proposed. A 10GBaud 9QAM is de-aggregated into two 10GBaud PAM3s and a 10-km short-reach transmission is performed before signal detections.
