Coherent optical communication systems

Introduction to Fiber-Optic Communications, 2020
This chapter is focused on the discussion of coherent detection techniques of optic communication. By mixing with a strong optical local oscillator (LO), the optical signal is effectively magnified at the receiver, and coherent detection also allows the ...

Scheme of coherent optical chaos communication

Optics Letters, 2020
We propose and numerically demonstrate a scheme of coherent optical chaos communication using semiconductor lasers for secure transmission of optical quadrature amplitude modulation (QAM) signals. In this scheme, a laser intensity chaos and its delayed duplicate are used to amplitude-quadrature modulate a continuous-wave light to generate a chaotic ...

Convolutional Neural Network-Aided DP-64 QAM Coherent Optical Communication Systems

Journal of Lightwave Technology, 2022
Optical nonlinearity impairments have been a major obstacle for high-speed, long-haul and large-capacity optical transmission. In this paper, we propose a novel convolutional neural network (CNN)-based perturbative nonlinearity compensation approach in ...
