Secure optical communication using symbol-by-symbol time-domain spectral phase encoding with QPSK modulation

Abstract

© Asia Communications and Photonics Conference (ACP) OSA 2019 We report the experimental demonstration of a secure optical communication system using 40 Gbps coherent quadrature phase shift keying modulation. The security is implemented in physical layer using symbol-by-symbol time domain spectral phase encoding.EPSRC Quantum Technology Hub in Quantum Communications (reference EP/M013472/1)
